I'm trying to sort through the plethora of information available on
multiband HF verticals and
basically I'm after some recomedations on what to get based on my
restrictions.
I dont have a big plot of land and can't fit in a multiband dipole
unfortunately. Due to
various other pressures I can't put a vertical with radials up high.
(an "eyesore")
I've got a 50' X 50' (14.5m X 14.5m) fairly flat (gently sloping -
about 7 degrees) corrugated
steel roof and I'm hoping I can put something low over the middle of
this 2500 square feet of
steel.
Would it be appropriate to mount something like a Butternut HF9V,
Diamond CP6, HyGain DX88 or maybe a Hussler BTV5 as close as possible
above the middle of the roof with a total height above the ground of
about 15 feet and electrically connect the roof to where the radials
normally would go and use the roof as a ground plane?
I've alos read that I should place the antenna feedpoint as close to
the roof level as possible. Ie not elevate it at all. Would others
agree?
Which of the antennas listed (or any other multibands you can think
of) be best for my
installation?
My only other alternative is to put a ground independant antenna
(Comet CHA250BX or similar)
about 8m (25') up on a pole off to the side of the house. It's not
out of the question but
the ground independants like the Comet seem to get some pretty bad
reviews and I'd rather use
a "normal" antenna, or as normal as possible.
Any other thoughts or recomendations gratefully accepted.
Thanks,
Dene
