Topband: Shunt Feed

[Mike(W5UC) & Kathy (K5MWH)]

Greetings fellow Topbanders:

Please, an antenna question.  For the last several years I have use a 
Inverted L on 160.  Rscently I became able to run more power (from 450 
watts up to 1 KW output.  At that point it appeared that I had developed 
an arc somewhere in my antenna system, so I abandoned the inverted L for 
shunt feed of my tower(which many years ago, I used successfully),  I 
have been able to successfully match the Shunt Fed tower using a Omega 
Match'


So my question is:  How effective is a Shunt Fed tower, AND, is it more 
effective than the Inverted L?
