[Elecraft] Rx antenna protection

[Phillip Zminda]

Paul,

I have used a BOG, a Pixel Loop and a Wellbrook loop receiving antennas. The BOG was ok but signal levels were very low and it needed a preamp. The BOG needs a lot of tweaking and good grounds at both ends. K1FZ is the expert on BOGs and can provide a wealth of information as well as custom transformers. I used it one winter but didn’t want to leave in the yard when mowing season started. The Pixel loop worked fairly well but I sold it and got a Wellbrook ALA 1530, which I think has a cleaner design. The Wellbrook works quite well at reducing the noise level. The signal levels are lower but with much reduced noise. My loop rotor died and it’s in a fixed position but at about a 6 ft. height it doesn’t seem highly directional. I think the Wellbrook is still cheaper than the Pixel. Andrew Ikin at Wellbrook is very helpful in answering any questions about loop applications 

My receive antenna is far enough from the transmit antenna that I have never had any issues with the COR activating, even at 500 watts.

Good luck with your choice.
