WebJan 4, 2024 · When the antenna is built, you just put it on the ground and attach a feedline. Almost TOO easy. Construction of the LOG Antenna. Other than wire, other components needed for this antenna are an impedance transformer (~ 5:2 turns ratio), a couple common-mode chokes to reduce signal pickup in the feedline, and some RG-6 or other … WebMay 1, 2024 · Ferrite Chokes in the Antenna System. A transmitting choke creates a high impedance in the path of common-mode (CM) RF current that a feed line would otherwise pick up from a transmitted signal. That interaction is called coupling, and blocking the current is called decoupling. Coupling between a feed line and an antenna can distort the ...
