[TowerTalk] Antenna Ideas Needed

[Bob Maser]

I still need a base for a Tri-Ex LM354HD.  The Tri-Ex number is RCB70LT.  If 
you have one that you can spare, please contact me.

My plan is to put up a HyGain 205CA in a 4 element configuration, modeled 
with YO. I need some ides on putting another smaller beam above it the would 
work on 15, 17 and maybe 10.  I'm thinking that a 10/15/20 tribander would 
work well by changing the 20 meter portion of the tribander to 17M.  Has 
anyone on this reflector done that and which smallish tribander was used? I 
plan on spacing the top antenna at least 8 feet from my 205CA to minimize 
any interaction. My thinking is  that since the lowest band is what I want 
to up in frequency to 17M, all I need to do is shorten the 20M element tips. 
Good idea or bad idea?
