If your HF9V is mounted 10' above the ground, how in the world can you
adjust the top items? I use a turner with mine; works great. Watch out
for 80 meters. No radials cut for the band, 2.5:1 SWR width is about 150
KHz, with best SWR 2:1. Adding ONE 80-meter radial, very sharp peak (SWR
1:1), 50 KHz bandwidth. Tuner compensates.
