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.
