Round here my level of QRM on my RA17 was vastly reduced by moving to a vertical longwire.

Since most house wiring, networks, burglar alarms have the majority of their wiring horizontal I figured a vertical mast might give me a better result. I bought a 10m telescopic mast and my RA17 has never been so happy!!
