Looking for the very best 2M/440 dual-band mobile antenna made.
Looking primarily for the highest gain on both bands. Mounting and
size (length) are not important, i.e. can be anything.

Any suggestions?

Thanks...

Or possibly a Cushcraft A27010S?

Hmmm ... that's a beam, right?

Probably not easy to use mobile (portable, maybe).

Right. 5 elements on 2 meters, 5 on 440.

True... but the original posting made a point of asking for maximum
gain, and said that type and mounting weren't important. Nothing was
said about "omnidirectional" one way or the other. (##grin##)

I wouldn't by any Cushcraft antennas produced since Joe left. They
don't have the same reasons behind their designs anymore. Like quality.

Realising its not what you are after..

- You live in very flat country? Be careful of high gain if you have hills.

- Dont use directive antennas on the mobile (eg a quad/yagi) as most
comms on VHF/UHF happen by reflection once you are beyond LOS and in clutter

- Height above ground clutter is VERY important. Whatever you end up
purchasing see if you can put it on a very high mount. (Even to the
point of mounting a 6ft poll on the vehicle and the antenna on top of
that - you did say length wasnt important!)

Not particularly flat ... (MA)

Right, I should bave been more clear, I'm looking for an
omnidirectional vertical.

I once had a Hustler 2-meter collinear, something like 5 db gain
omnidirectional, and five feet tall or thereabouts, with a 3/8x24
mount. Never had a better 2 meter mobile antenna before or since.
But, it only comes in a monoband version, and only 2 meters and 220.
If I could find something dual-band for 2 and 440 that's as good as
that one was, I'd be happy.

Gee I am gong to have to learn those state abbreviations... So many of
them start with "M" grin

I use to work on UHF radio equipment installs being used on the flat
areas in western NSW (Australia). One of the common setups was a 9dB
fibreglass whip (476MHz - about 6ft long). It had to be setup just right
otherwise the few degrees of tilt you got from air movement would lift
the pattern in front of the vehicle above the horizon and make it all
but useless.

I also hear that 1/4 wave whips are almost essential if you are driving
amongst high rise buildings.

Also did some tests recently on the "gain" of a vehicle mounted 1/4 wave
vs a test dipole antenna at 4 metres height. There was about 10dB
between them, we assumed because the 1/4 wave was still very much in the
ground clutter. This was on 149MHz and LOS.

My view is that any dual band antenna is going to be a huge compromise
anyway and high gain on both bands unlikely. I am however prepared to be
shot down over this!

Apologies for waffling on!

the best antenna is a dual-bander mounted in a hole drilled in the
middle of your vehicle's roof...
