Hi,

I would like to reposition my 2M/70cm Vertical (Diamond X50) to a higher
position.

One option is to mount it above the TV aerial, I understand that the signal
radiation below the antenna is very small, does anyone have any experience
of a similar setup?

If so what kind of distances would you suggest between the antennae?

Obviously my main concern is TVI and poorer performance from the Diamond due
to its close proximity to the TV aerial.

I'm using RG-213 for the Diamond and normal coax for the TV.

Any help or suggestions would be appreciated.

Cheers,

Paul


Are you in the UK or USA? Very different problems between the US VHF TV and
UK UHF TV. Advice which is excellent in the US just doesn't apply here. E.g.
we no longer have any VHF TV so VHF considerations are not applicable.

UK TV is ~ 470 - 615 MHz (Band IV) and 615 - 860 (Band V) so low Band IV
signals are quite close to 70 cms.

Best advice is to try it. If problems arise then there are some fairly simple
cures.
