[TowerTalk] How close?

Depending on what antenna(s) you have on your tower, it may be resonate on 
80m, possibly causing some problems on that band.  If a vertical 20' from 
your tower is your only option for 40m and 80m, I would go for it!

How bad would the interaction be between a raised vertical (BigIR III w/80 m
coil) and a 45-50 ft tower that is 20ish feet away.  Vertical will be apx 
10'
above ground with resonant radials on 40 and 80 (2 each)...I know ground 
mount
with 60+ radials is far better but this is all I can do for now.  Will I be
wasting my time?  Suggestions?

Thanks,
