[TowerTalk] [YCCC] interaction from low-band wires

[Mike McCarthy, W1NR]

I have never had interaction problems with inv-V's at the top of my 110'
tower.  However, I would go with an 80m V and shunt feed the tower for
160 which is what I have been using for years.  Had a 160 V that didn't
work worth squat vs. the shunt feed.  Of course, I have a Heathkit
remote antenna tuner on the 80m V to cover the whole band.  You might
want to break the ends and use a jumper to change the length for CW and
SSB.  An 80V at 110' performs really well.
