Hi,

I have up a Butternut and as mentioned in other replies the antenna is good
when it is adjusted right. Follow the instructions to the letter and advice
from the replies here.

You mentioned a roller inductor in the match box and assume you are trying to
use a tuner with the antenna.  Do not use the tuner and spend your time on
adjusting the ant w/o the tuner.  It will take a lot of time and effort. As
mentioned the best I found it mounting up about 10 ft or so and elevated 
radials
with at least 2 per band.  Read the application notes on the Butternut web
site also as they are of benefit.  Watch your connections as to aluminum to
aluminum and use something like Penetrox. The analyzer will work fine at the
end of the length of matching coax.

I do NOT use a tuner and ant works fine after a week of adjustment until the
trimmers came thru the apple orchard and took care of the radials.  Had to
redo most and now seems back ok till next time.......  HI.....

Ant seems flimsy but has held up well thru ice and wind storms.
