    Antennas are a very important part of a radio station, from big beams on high towers to simple masts on urban houses. They are exposed to the changing weather conditions, mechanical strain, UV radiation, humidity etc. The antenna mast or tower design and installation present a challenging task due to a number of factors that have to be taken into account.

    Durability and safety are of prime concern so as to ensure the antenna remains fully operational for a long time. The right guying is therefore extremely important. Steel guying wires are still very common, however they are heavy, difficult to work with and their strength deteriorates with time due to corrosion and general ageing. Their electrical conductivity is an undesirable feature as this interacts with the antennas and deteriorates their radiation pattern. Thanks to the recent developments of materials, both amateur and professional users are changing over to non-conductive guys and ropes and will never go back to using the steel wires once the benefits are fully appreciated. The non-conductive synthetic fibres have all the necessary qualities: high strength, negligible elongation but with good flexibility, long life, low wet-ability, minimum bending radius giving the ability to tie knots, good UV radiation resistance, weather durability and resistance to acids and alkali.

    Mastrant optimized lines are made from proven modern materials such as Polyester (Mastrant-P) and Dyneema (Mastrant-D and D-F2). The range covers products for a variety of applications, from thin support lines used for tying wire antennas and beams, to guys for supporting small and portable masts and vertical antennas, to anchoring ropes for high antenna towers tens of metres high.

    The product line is supplemented by a wide range of stainless steel accessories. The development, testing and quality control of all these products ensures a superior product delivering long life. They are subject to continuous tests in laboratories as well as in real conditions of use, in co-operation with a number of professional users.
