MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)

MASTRANT-M is the choice for those who require a thinner rope with high performance at an affordable price. Very high strength, negligible elongation, very low weight, and great abrasion resistance - are all attributes that make this rope a perfect for guying. It is a highly durable rope with an outstanding performance-to-price ratio. Of course is nonconductive (no effect whatsoever on your antenna).

MASTRANT-M ropes using new Dyneema® Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema®, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema® Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema® fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema® also to the markets of permanently loaded applications like guying of towers, masts and antennas.

Construction:  Double braided rope
Core: 100% Dyneema DM20, braided.
Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up).
Outer cover: Polyester

Ropes by length: The ropes sold "by length" (not on spools) are packed in hanks. If you order for example 30 pcs of item "1 m", you will get 30 m (99 ft.) of rope in one piece. The ropes on spools are always less expensive than "by lengths".
If you are working on a complex project and need several different lengths, let us know. We will try to find an optimal solution for you.

 

As your interest in the hobby grows, you will find other uses for any excess rope i.e. try another antenna or pass along to a fellow club member? Some of us, personally, use our excess rope all the time and they are glad to have it - splice sections together all the time :)
