We are updating the ratings for Breaking Strength and Safe Working Load for our most popular rope, 4mm and 5mm Mastrant-P. We began improving the construction of this rope in our production process more than 6 years ago and have been testing samples from each run. We are now satisfied that the changes have resulted in consistent, permanent improvements. Here are the new ratings: Mastrant-P, 4 mm: BS=440 daN (about 440 kg, 970 lb.), SWL=132 daN (about 132 kg, 290 lb.) Mastrant-P, 5 mm: BS=540 daN (about 540 kg, 1190 lb.), SWL=162 daN (about 162 kg, 360 lb.)

We have added to our assortment (hardware section) very useful material for all who build their antennas yourself. It is stainless steel (AISI 316 - A4) thread rods 1 m long in sizes M5 to M12.
