Our story

The Mastrant brand was created in 2007 with the participation of experts in the development and production of synthetic ropes, and in collaboration with several experienced HAM. We started with two rope product lines and a basic range of accessories. We now have over 300 items in our range and supply solutions worldwide. In addition to ropes, we produce several accessories - such as mast clamps, guy rings and most recently ground pegs. We also provide consultancy services. We support amateur radio expeditions, contests and WRTC (since 2014).
