You can twist the wires from you loop to your phono plug. Several turns per inch should suffice. You should have a nice broad frequency response with that...
Hello: Suppose the Height/lenght > 1, will the antenna be more directional than with a Height/lenght <1 antenna?? My idea is that n,ow I'm always using a...

I have used all 4 methods including using the toroid feed. I've seen no difference between the Faraday shielded feed loop and the bare wire loop, so I use bare...
Hi All I'm looking at a Wellbrook AL-330S. I know they can be mounted on a rotor and show some rejection. Do they reject when the loop is facing the noise or...
Hello Ken The side is rejecting this "|", the other side "O" is what makes the best capture. The band rejection is 80% in the "|". Respectfully Eduardo L....
I'm sorry, I did a reversal of position, but to be sure, see the drawing. Small loop antennas have patterns opposite those of large loops. The minima, or...
