[Skimmertalk] [dxatlas] Antenna for Quicksilver Receiver

FWIW, I'm using an 8-foot active vertical, and results are quite 
acceptable, although I could doubtless hear more with Beverages on 80 
and 160.  The big advantage of this approach is that you don't miss 
openings because your antennas are pointed the wrong direction, and of 
course you avoid the risk of feeding 1500 watts straight to the QS1R.

The protection strategy you describe makes sense to me.  Having that 
protector between the relay and the QS1R should prevent any transients 
from less than perfect relay sequencing, though it would be good to use 
a PTT output that leads RF production if you have that sequencing available.
