Yes - I used a F12 Magnum in AZ at 136' and now here in SC at 144'.... it 
doesn't play particularly well on 160 RX. The Hi-Z is much better. That 
stated occasionally I'll hear DX quite nicely on it ...

Has anybody tried using a 80m rotary dipole as a 160M  RX ant ?   Im 
thinking it may well be quieter
than any dedicated RX ant I could come up with....on a city lot.   There is 
no way I can get adequate
separation between any 160m TX ant, like a .25 wave sloper,  shunt fed 
tower,etc, and a 160M  RX array.
This assumes plenty of Z and esp RS on the 80m 1:1  choke balun... when used 
for 160M RX.   I dont use
QSK, just vox.  So I would have to incorporate some high speed vac relay 
setup to swap ants when on 160M RX.
It would be interesting to know if the  RX concept even works.  80m rotary 
dipole planned to go up this spring, on the
crankup..at 100 ft.
