Works well 80m down to 500khz but being so close to the ground its a bit deaf above 80m as you would expect. My understanding is that for hf it should me mounted high up but for lf its better low down near the ground. A rotator isn't really necessary as the beamwidth is quite broad but where I do find it useful is nulling out the local qrm, switch modes etc. >I can hear NDB's nothing on 500kHz By NDB I assume you mean the 200/300khz variety so if you can hear them, 500khz shouldn't be a problem. I recent wspr activity on 500khz I found I could hear everything that others were hearing...at reduced strength of course, but then I don't have the room for "big gun" antennas here :-) 73 Trevor G0KTN
