Topband: Shunt Fed Tower

[Gene Smar]

Jerry:

     Here are a couple of poostings I made after I built my tower and 
shunt-fed it back in 2002: 
http://lists.contesting.com/archives//html/Towertalk/2005-12/msg00636.html . 
I did not install a second set of shunt wires for 80M as I said I would in 
these postings.  Instead, I installed a half (WL)-sloper wire for 80M at 50 
feet and it works just as well as my Topband shunt-feed system.  But you 
could install a second variable cap and set of shunt wires on another tower 
face for 80M; others have done so.

     Let me know if you have any other questions.  I've been saying that my 
shunt-feed works better than I had ever expected and it outperformed my 
Inv-L on the band TX and RX by 5-10 (measured) dB.

I’d like to try shunt-feeding my 60-foot freestanding tower on 160M and 
80M..... how can this be done?  If you’ve done it successfully I’d be 
grateful for the specifics, or maybe a reference to the construction article 
you used.
