Roof-mounted Butternut Vertical
« on: August 14, 2000, 03:24:45 PM »

I use a roof mounted Butternut HF-9V.  My roof is metal, because I live in a Mobile Home!

I mounted the antenna on a 16' 4x4 post at roof level and about 4-6" away from the roof.  I grounded the antenna to the roof with a ground strap and a sheet metal screw.

I have been very pleased with the performance.  I never wanted a vertical, but it is the only choice that I have in this neighborhood.  Now that I have tried it, I can't beleive how well it works.  Even on 75 meters.

73,

I want to roof-mount a Butternut HF9V vertical.  I read the product reviews, but didn't find any specific mention of a roof-mounted Butternut vertical.  Does anyone have any experience with Butternut's roof mount kit (RMK)?  Is it worth the buck$?  I am open to suggestions, as this will be my primary HF antenna (I can't put up a Yagi).

I had very good luck with my 6 band butternut mounted on my roof.   I used a 4 foot tripod mounted in middle of roof. I used 4 radails for each band and had them hung down and away from the ant.  Really, I think i was working like a ground plane.   I use a 1/4 wave length for each band if I remember right.   Tricky part is tuning.   I had a 10 foot mast into the tripod and had to use a 15 foot ladder on roof to tune the coils.

Just attach 1/4 wave radials to the antenna ground side for each band. 2 minimum and the more the better! I have found that 8 per band gets you the most bang for buck spent on wire. If you would like to build a remote tuner for your butternut antenna and tune the element and not simply the feed line on 40 and 75/80 meters drop by my web site at http://n4zou.homestead.com from there you can click on a link to the information. The tuner is really simple, it's only one motor driven capacitor! It uses the 80 meter coil already on the element for the inductor. Good luck and 73... Scott
