Trap on Coaxial Cable: by Igor Grigorov, RK3ZK
If a multi-band antenna or a symmetrical antenna is installed at insufficient environment it is possible when the antenna works to transfer, a part of RF energy is reflected from closest subjects to the antenna itself and to the braid of the coaxial cable of the antenna. From the braid of the coaxial cable the energy goes to ham's shack and causes damage to all radio equipment in to the shack.A trap on the coaxial cable helps to eliminate the sneaking of the reflected RF- energy to the shack.
