What difference is there between Mastrant Classic ropes (P, Q, S, C, R) and Mastrant-M? 
The difference stands in parameters. Ropes from the Classic product line are the basic ropes optimized for a good price to performance ratio, whereas type M has approximately doubled strength and simultaneously half the stretch compared to type Classic. They are also lighter because the rope core is made from high-strength Dyneema^® fibers.

When is it better to use Premium rope (M) instead of Classic? 
When one needs the lowest weight and wind resistance (long ropes holding wire antennas, or supporting large beam elements, or expeditions where low weight is crucial). Also when the anchor points on the ground need to be placed close to the tower (less than 50% of the anchor height – depending on the type of tower – the higher stress needs to be calculated individually) and finally, for any big towers with big antennas.

When I am looking at Dyneema ropes for maritime use, the strength eg. with 10 mm Dyneema is well over 10.000 kg, but your Mastrant M rope with a similar diameter has "only" 3850 kg strength, even the core material is the same. Can you explain why? 
There may be several reasons for this difference. The first is that in Mastrant-M ropes, HMPE fibers form only the core. The braid (and any intermediate braid) is made of Polyester fibers, which have lower strength (but other necessary properties for which they are used). The reason may also be the methodology of measuring strength. Our declared breaking strength of ropes is strength really measured – each production series. It must be always 3% or higher than in our specification. There on the market is also another approach – the theoretical BS calculated based on the specification of Dyneema fiber and number of fibers (diameter). This theoretical strength is always much higher.

What difference is there between Mastrant ropes and Kevlar ropes? 
Kevlar, like Dyneema^®, uses high-strength fibers. While Kevlar is made from aramid the Dyneema^® is made from a special sort of PET. Kevlar is not UV resistant and its fibers tend to break when bending over a small radius.

Can you compare Dacron with your ropes? 
Our ropes have a cover made from polyester. Polyester is a material, and it is the same material as Dacron (brand name of polyester). Construction of the rope (number of layers, number of strands, fiber angle, manufacturing process, ...) is a different story – the design of Mastrant ropes is adapted so that the abrasion resistance is as high as possible.

What is the expected lifetime of Mastrant ropes? 
Like steel ropes producers, we recommend replacing them after 5 years of use. However, we have experience with flawless 15-year-old installations.

Do I need to buy a complete reel? 
How long is the rope on the reel? Standard is 100m or 200m of rope on the reel. Some diameters are 31m on the reel. However, we can deliver any length you want (ropes longer than 200m are available on special order). The ropes of standard length are cheaper. Aside from standard ropes, we offer also “ready-made” ropes with thimble compressed-in on one end.
