Long wire antenna random wire - w8jiThe balun must be a high quality current balun, not an unun or voltage balun. It should be a 1:1 ratio with high common mode impedance and high voltage breakdown. The coaxial feed line, since it operates at high SWR, should be high quality and as short as possible. Ideally the counterpoise wire should be elevated above earth.
8 hours ago · long wire antenna reviews, Open wire feeders are popular with the ham community once again. The old school handbooks of a bygone era have lots of configurations for you to try.
