I have a Hy-Gain Hy-Tower vertical working on 7 bands. It has stubs
attached at various locations on the tower portion. With this arrangement
longer is lower in freq. as in many other situations.
I have 4 each 10 ft sections of Rohn 25 and a 9 ft top section. My current
thinking is to erect it on insulators and try to build a DIY version of the
Hy-Tower complete with multiple stubs. Anyone want to mention any pitfalls
or difficulties I might encounter?

Subject: [TowerTalk] 80 meter stub
Hi All
I've been making some more stubs, but in doing that, my MFJ-259B died.
I cut one for 80, just using measurments determined by VF, etc, and came
up with a stub (length (I know it's probably not spot on).
The problem is, when I connect it, it moves the 1:1 SWR point from about
3560 (where I want it) down to about 3470.
Does that mean the stub is too long? Thanks and 73
