I have a Cushcraft X-7 which is not a pure LPDA but uses a log cell. It is fed thru a 4:1 balun and I route the coax along and taped over the boom (the tx line is below the boom). Except on 10m where
Adhesive tape tapes coax just fine to round member towers, but I am having a hard time taping coax, rotor cable, etc to the members of my tower which are all flat. Any ideas? Thanks, Juan EA5RS _____
I have two close-spaced (30 km) QTHs One is inland, 30 km from the coast, city location, HF horizontal antennas 40m high (top of building) The other is just 200m from sea line, sub-urban location, si
I have developed a simple method to accurrately measure signal strength difference vs time of two HF signals. This method can be used to check signal strength difference between two antennas or stati
Or simply use a dipole for an antenna in HFTA and multiply (natural units) the resulting pattern by the free space pattern (in dBd or dBi-2,14) of the actual yagi being used. Yes, I agree the result
