Hi Topbanders,

Here's something that's bugging me, and perhaps a few of you fellow snow-cats 
can give me some advice. 

I'm considering a triangle of MA160V's (Cushcraft) along with radial plates on 
each. The problem is that here in Southern Colorado, we receive about 4-8 feet 
of snow during the winter. It seems obvious that I can't ground mount the hot 
side of the vertical because it will get covered up. SO, I'm going to raise it 
up by mounting it on top of a steel tube that runs down into the radial plate. 
It would look sort of like an umbrella stand for your outside patio umbrella.

I'm not familiar with this antenna yet, but--what will happen if I raise the 
feed point up? I'm thinking that the 7' tube, being connected to the radial 
system will work as normal. Will the elevated feed point affect the impedance?

Any comments on this idea? 

Regards to all,
