[Elecraft] RX antenna protection

[Vic Rosenthal]

I'm using a Pixel Loop. Advantages are that it is small, can be rotated to null a noise source, and works on all HF bands. It is vertically polarized, so if you have a horizontal antenna you can get a useful diversity effect without too much physical separation. It has a built in relay that disconnects it to protect your receiver while transmitting. I use diversity almost all the time, and it definitely improves copy of CW signals.
