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.
73 and Happy Holidays, Jerry K3BZ
