 Gary,


I have the same Butternut mounted 8' above ground.  It's on a 10' galvanized
fence post in 1.5 to 2' down, in concrete.  There's another one "dropped"
down inside of it too.  It has 16 radials, all sloping at approx 45 degrees
from the base.  There is 8 on 20m & 8 on 17m.  There is also 3 on 75m laying
on the ground.  It's mounted too close to the fence to do 360 degrees of
radials on 40 & 75.

I 1st used the multiband radials on the mfg site, didn't work worth a darn.



I've got some pics, e-mail me ... forrestw@gbis.com

Hi, 

An update on the Butternut. I wasn't able to get it up on the roof. 
The legs of the tripod are rusted and it's unsafe and I'm going to have to
remove it. 

To experiment with the HF9V I mounted it on top of a pole in the back yard
where the base is 8´ off the ground. I do want to get it up higher in the
air so I will use interlocking aluminum poles to do so (one end slides into
the next tube & so on). 

The pole it´s on now is in cement and was a pole for a bird house. 
I´ve figured a reliable way to use the existing pole as a base and by
loosely tying a rope around the aluminum pole and the cemented one, I can
lift it enough to keep inserting pole after pole and it won´t fall over. 

I have some Dacron rope & will use that to guy it and will make the 80 meter
radials extra strong and use them for guying as well. 
Seems like the bands have been very quiet the last few days so I´m not sure
how well the antenna going to do for me but it should be fine. I made six of
the multi band radials from 300 ohm ribbon line seen here
http://www.bencher.com/pdfs/00408IZV.pdf I will make four 80 meter radials
as well. I forgot there is a required 75 ohm matching stub and I have to
order the RG-11 today. Once I get that in I will raise the antenna. I´ll let
you know how it´s doing. 

Thanks for the on & off list replies, I appreciate it. 
73,
Gary
