The best vertical antenna that I have owned was a Comet GP series for 2 Meters,
plenty of gain and built to take the weather with the connector 'inside' the
The length question makes me think a mobile antenna on a 'ground plane' might
be better for you, Paul.
The owner of Radio City ( Previously known as Satellite City ) once advised me
that for the K4000 motorized mount, those dual-band antennas which had matching
wavelengths to the recommended ones would require less in terms of a 'metallic
ground plane'. The Diamond site would suggest antennas with NMO mounts such as
the SG-7500(x). Comet/Maldol/Diamond all seem to make this sort of thing, yet I
would avoid the 'foldover' feature for your roof. The motorized mount requires
regular tightenting, and antennas with foldover may not be good for your roof.
The Larsen brand of mobile antennas seems to be very popular for less
maintenance than the ones previously mentioned. I had no experience with
I have been a regular contributor to the tech forum on www qrz com on mobile
and VHF/UHF. The 'expert' there seems to be K0BG, who hosts his own website
regarding mobile installs.
Just a few other thoughts:
A horizontal yagi in the attic pointed at your favorite repeater might be
better if it is over 25 miles away. QST had an article on Rayleigh Fading which
explains some of the distance problems, yet there was a small math issue
reviewed later- be sure to get the correction if you would provide it to
others. I had a good signal with a Cushcraft yagi ( dual-band - approx. 4
elements on each ) in the attic even with snow and rain up North. I recommend a
better cable, such as LMR-400 ( if the length exceeds 40 feet ) to avoid
approx. 1/3 wasted power at UHF frequencies.
There are many 'disguised' antennas which look like plumbing vents and the
like. If you are going to penetrate the roof, look at the condition of the roof
( re-shingle soon? ) or consider using a soffit vent.

Subject: [BVARC] 2 meter base antenna
I need suggestions !!! I need a 2 meter home base vertical antenna. Not to long
the dreaded HOA ! Was looking at the Hustler G6-270? I know it's a dual bander
but it is supposed to get 6db gain on both bands, is 5/8 wave and is only 7.5
ft long. A little longer is ok. Would like to keep it a one piece if possible
but not a necessity.
Please, any suggestions will be considered !!
Love your pets, they want and deserve it !!!
