Well, you could try a magnetic loop antenna. They don't pick up
electrical noise (hardly at all). You have to build them well
(i.e. very low dynamic resistance) for transmit as the radiation
resistance is v. small, but you could experiment with a simple
one made from co-ax braide and a small capacitor to try out the
difference on receive.

I saw an article once from someone who /M used a loop on RX and
a whip on TX - because of the noise level.
