[TenTec] Omni VII, Antenna tuning, etc.

[Clark Savage Turner]

Oh, heck, I've beaten up a Dentron Super Tuner on 160 with my OMNI VI 
and no amp at all.  100 watts into a short vertical - it DID get the 
SWR down at the rig but the SWR would "creep up" with heating of the 
elements inside.  I tried another one, same thing.  I suspect many of 
the MFJ units would do the same.  Their cheaper tuners are "fine" as 
long as your antenna is relatively well behaved (I've done fine with 
the Diff-T tuner from MFJ even with an amplifier, but never a difficult 
antenna!)

Yes, then I went to the 238 and it worked fine.  Now, I don't use amps 
anymore, and my main tuner is the Harvey-Wells Z match, rated for 400 
watts (AM!!!) and just hit it with 5 watts most of the time.  No 
problems here.
