Bob ---- I rest my case. You got a lot of different opinions. Try it and
let everyone know how it works.

Subject: Re: [TowerTalk] Ground mounting vs roof mounting verticals
Now you have my attention, I have a tuner. One built into the rig and
another external for QRO.
I am thinking more and more 'try mikey you might like it' may be the way to
go on this one. It is really no big deal to mount it --
take maybe a couple hours most.
No just to pray for no rain or wind.
I was going to do the TitanDX Vertical but it is so high profile that it has
to be guide-off, the Butternut doesn't because it is
tapered in such a way that it catches very little wind.
