I have a 6m/2m/70cm Diamond V2000 and a 2m/70cm Workman (that looks a lot
like the V2000). I'm getting 2:1 @ 2m on both of these antennas. (1:1 @ 6m
on the V2000, I don't have an SWR bridge for 70cm).

My 2:1 sounds high, certainly 10:1 is too high.

Is anyone getting better than 2:1 @ 2m with the V2000?

Hi

I have not had much success with a commercial tri band 6M/2M/70cm
vertical. I hope you know the type I am refering to, 2.5M high with
three radials, looks like two for 70cm and one loaded radial for
6M/2M.

I have never had any success with this antenna in the attic so did
some experiments with the antenna on a 8 foot glass fibre pole in the
garden. SWR and radiation were perfect until I rotated the antenna
with the loaded radial facing the house about 20 feet away, then SWR
climbs to 10:1 on 2M but is still perfect on 70cm ???. Not tried 6M
yet.

Any idears whats happening ?.

Your antenna sounds as though it is a Diamond V2000, or Comet equivalent.
If so, those are not radials, but decoupling stubs. Furthermore, the
antenna was designed to be mounted on a metal mast, not a non conducting
mast. I suppose you could run a length of wire alongside the non
conducting mast to give it the metal that it needs.

I suspect that your high swr situation has more to do with a loose
connector than with the decoupling stub pointing at the house
(coincidence).

I used to operate with a Diamond V2000 some years ago and it did need to
have the mounting mast capable of electric conduction, IIRC.
