Mastrant Guy Ropes

Mastrant 'P' Guy Rope

The correct rope is one of the most important parts when guying a tower. Mastrant supplies ropes which have ben specifically selected for mast guying. Important features are good UV resistance, a high tensile strength, low stretching and a first-rate weather resiliance. The Mastrant ropes are made from Polyester and Dyneema, which have been designed for high and permanent loads.

WiMo offers two different rope types, which are differentiated by their elongation percentage. The table below should help you in selecting the right rope and accessories for various applications - from hanging a wire dipole up to securely guying a large tower. The rope type Mastrant-P is made from Polyester, is offered from 2 to 6mm and has a slightly higher elongation under load. This rope is very well suited for wire antennas, light masts etc. The rope type Mastrant-M is made from Dyneema, has a very low stretching under load and is available in diameters from 1 to 8mm. Depending on the diameter nearly all applications in amateur radio can be covered with these ropes.

Mastrant Rope Thimbles, Shackles and Clamps

Mastrant Shackles and Clamps

The correct attachment of the end of the rope is highly important for the longevity and security of the guying. It must be ensured that the rope can not be frayed by movement and wear on sharp edges. In most cases the rope is held in a thimble and fixed by one or multiple screw clamps, most ideally with a double clamp. In addition to that the very end of the rope should be protected against fraying (fan out) by using another clamp or a cable tie or adhesive tape. The thimble can then be hooked up to a chain link or a carabine. When the attachment point itself is smooth and has no risk of fraying the rope then the rope can be attached directly to the lug without using a thimble. But please note that the breaking load of a rope is drastically reduced when tying a knot, depending on the knot by up to 30 or even 50%! So the use of a thimble is helping under thsi aspec tas well. Although the breaking load is reduced also when using a thimble, it is not reduced as much as when using a knot.

The mounting hardware by Mastrant is in most cases made of stainless steel type A4, i.e. a steel type which is also resistant against acid and seawater. This is not only beneficial on board a ship, but also on land, for example close to the sea. But even anywhere else exhaust fumes from chimney can lead to acidic precipitation which can harm metals. Please select the size of the mounting hardware in accordance to the rope thickness.

Mastrant - Rope Pulleys and Guy Fixation

Mastrant Pulleys and Brackets

When working on the mast guying, often the question for other mounting options arise, for example how to install wire antennas etc. Mastrant offers a large range of options for installation a fixation of such material.

Rope pulleys are useful to easily raise and lower wire antennas. This makes it very easy to experiment and adjust the antenna to it's mounting point for best performance. Or you can build a system with a weight to keep the tension of a wire antenna over a tree.

'With Swirl' means that this pulley has a rotating lug at the top. This helps to prevent twisting of the guy wire.
