[TenTec] Confusing Remarks

[RICHARD ANDREN]

This is kinda directed to Scott at TT, but I though it may interest the 
whole group.  First, a little history.  Going back a few weeks ago, I asked 
this group about protection of the auxiliary antenna input from a loop.  A 
bunch of emails bounced around, and Scott from TT mentioned that protection 
of the aux input is necessary.  He also mentioned that before you connect 
any antenna up to the radio, you should ground the hot lead of the coax to 
drain off any lingering charges since Scott had a blown front end from this 
very thing.  Now comes the confusing part.

All my coax's run through a bulkhead in my house to the back of my TT 
auto-tuner.  I don't remember the model number, but it was the only auto 
tuner they made a few years back... also called an antenna coupler.  Anyway,
 touching the center lead of the coax to the bulkhead is no problem after a 
disconnection for a storm.  But here's the catch.  The antenna switch 
inside the tuner is not the shorting type, which means that every time I 
switch antenna's, they could have built up a voltage potential, thereby 
blowing the front end as happend with Scott's radio.

Do any of the other TT tuner's use non-shorting antenna switches?  Should I 
replace the switch I have?  Does TT have the proper switch of the shorting 
type?  Will a shorting type switch wack out my C-4 pattern since the 
elements are close?  Am I asking too many questions?  Am I being a pest 
here?   : )
