[Elecraft] 160 meters RX antenna for K3 advice

[Mike Furrey]

In suburbia Houston, I was fortunate to have some nice very tall pine trees in which I had an inverted L with one elevated radial (up 20') bent to fit the 60' x 90' lot. It was fed through a ferrite bead balun. Power output was 600 watts. The rx antenna was a K9AY and one side of the rx antenna was about 6' from the radial! UGH! I 1) used rx protection; 2) decoupled the tx antenna by  a relay in the coax at the 1/4 wavelength point; 3) used ferrite bead chokes on the feed line of the rx antenna, at the antenna and at the rig. 
The K9AY loop has a broad rx pattern so when I set it up, it was orientated for the noise source to be in the null.

I tried a magnetic type loop and it seemed to work ok but the "AY" loop was better BUT I could play with diversity reception and occasionally that made the difference between hearing and making a Q.

My ON4UN low band handbook is highly dog-eared and I did manage over 150 countries at that QTH (now I am in the country).

 Regardless of which RX antenna you chose make sure to detune your transmit
antenna when receiving. This is especially important on a small lot where
adequate separation is not possible.
