Hello Daniel,

Thanks for your reply.

That's an interesting point, you are raising Daniel. Maybe I should 
write a little bit about the type of intended base antenna. This would 
allow us to better assess the situation of interference from TV antenna 
radials in close proximity of the 2m/70cm base antenna.

The antenna that would fit on the 5 m mast and would not exceed my 
budget could be a Commet Dual-Band GP-6 as described here:

I have also read some encouraging comment about this antenna on eHam.net 
here:

Is this type of antenna with ground radials more likely to be affected 
by radials of a TV antenna underneath? Do ground plane antennas still 
require a ground? Aren't the radials a replacement for the "missing 
ground"?!? Questions over questions. :-)

Salut,
