Re: [TowerTalk] R8 vs 6BTV, etc.

[Charlie <ad5th@direcway.com>]

I was in the same sort of quandary some months back that is, in choosing a 
multi-band vertical.  I happened along to www.dxengineering.com where the 
4-5-6BTV Hustlers are revered.  I purchased a 5-BTV along with the 60 
connection stainless steel radial plate and the tilt-over bracket mounting 
fixture.  I have read also many favorable reports on the Hustler BTV line.

As far as power robbing aspects I know of none. I have photos of my 5-BTV 
installation and swr plots at
1. http://www.ad5th.com/5-BTV.html

There are links on that page to the various items I used such as the "Direct 
Bury 9914F" low loss coax.  73 / DX
