If I suspended a few directors in front of a 10 meter dipole with a reflector of course, would that work?

I tried several times to get the mode A downlink of AO-7 to work for me. I tried a dipole, a vertical (ground mounted) and also a 3 element yagi but no dice. Next step is to get the vertical up at 20 or 30ft. and see what happens then. YMMV.
If it's for general antenna concerns, then yes but you wouldn't be able to rotate it in a very effective way :). I built a rotatable dipole for 10m once using PVC pipe and then running the wire alongside that pipe. Now one could of course build it out but then it becomes a matter of material as well in order to keep it stable.

Hi All,
I am using a vertical dipole, 10 m above ground for AO 7 mode A and I have good signals as soon as the bird is 1 degree above horizon. I think the vertical dipole provides better illumination towards horizon but of course has a null in the zenith, but that is anyway less interesting for dx on shortwave and Satellite.
Cheers Edgar

Portable in the sense that you can have it prebuilt out of wire with ropes at the end and haul it up in some trees.
And it comes close to omni directional with overhead coverage.
