If you are considering various verticals, why not look into one of the
SteppIr verticals?  I have worked countless stations using the BigIr, and
have several friends with the model.

Hi all: 

I've already tested my station through a dummy load and the reduced 20M
output still occurred. 
I have also tested the antenna direct when I was having that 75M SWR spike
and the numbers were: 
30/1 on 75M, 2.5/1 on 40M and 5/1 on 20M. I didn't try 17/15/12/10 because
don't operate very much on those bands. 
My own tuner failed to keep that spike down on 75m with 200W but had no
problems handling the rest of the tuning on 40 and 20M along with the 600W
CW output from my amp, except for 20M due to the low output. 
When my tuner returned from my friend's bench, after he did some work on it,
it handled my antenna perfectly on 75M but when I tried my amp, with 500W
CW, I heard a hissing in the back of the amp, not in the tuner or rig. 
I re_installed his tuner and everything was perfect. His roller inductor and
capacitor is much heavier than mine and I can't help but wonder if this is
why Zero Five recommends the Palstar or some other heavier tuner. 
They offer a remote tuner version but its only rated at 200W. I tune mine in
the shack with about 100 feet of coax. I've had a very good relationship
with Tom at Zero Five but if these antennas are truly a danger to equipment,
then I should look for the refund and maybe look into the Hustler 6BTV. 
I'll call Tom and Ameritron today and get this sorted it out. 
I'm very perplexed.
