[TowerTalk] vertical height

[Gregg Seidl]

Can anyone tell me what height of Rohn 25 is needed to resonate at 3.8 
Mhz?I'm installing an insulated from ground tower and using Array Solutions 
160/80 and 75 tuner.It requires that 75 be resonate then switches in coils 
to resonate on the other bands.I will be using 5 10 foot sections,one 
tapered top section and then whatever I need in 1 and 1/4 inch 
conduit(pipe).Jay says it needs about 60 60 foot radials which is no problem 
and I may have some longer then that and will most likely roll out some 
chicken mesh in winter.Just trying to minimize my tower climbing.  Gregg
