Re: Magnetic Loop Receiving Aerial (Gary Tempest)
For medium and longwave a single untuned copper pipe loop or square is in effect a short circuit across the antenna and earth terminals, no wonder it kills the noise, stronger signals will survive but much reduced so need amplifying...volts/amps per meter....tuned antenna is better, also loops are generally directional, more so at the lower frequencies, nailed to a fence it can only be orientated in one fixed direction, the direction of the fence...but which direction...transmitter or noise....for loop antenna a multi turn tunable loop that's rotatable for me, tuned antennas are the key, been the key since radio dot, even in 1910's W.W......Marconi etc.
Good luck whicheverways.
