Hi to y'all Right now I have a dipole in the attic over my apartment. It works fairly well but like most of us I want better.I live in a apartment complex and am wondering if a Imax 2000 or antron 99 hung horizontal in the eves of the attic would work??? The attic is approx. 25-30 ft off the ground. Thanks Guys & Gals GOD BLESS

imho i think a diapole made of coax would be your best bet.if ya cant put up an outside antenna

It's a shame when radio operators are limited like that especially when it comes to antennas. Frustrating too. Sandbagger is one of the antenna experts on this forum when it comes to theory, actual antenna operations in real life, etc; but I'll give this a try. I'm inclined to agree with hotrod. I don't know if your dipole set up is coax based or wire and coax fed. The coax method with the shield stripped back for half of the dipole and the center conductor for the remaining half and both cut to the proper lengths works fairly well indoors from my experience. If set up properly it should be directional no matter. As far as hanging a stick type antenna, there's only one way to find out, do it. I'm not sure if a ground plane or counterpoise without a balun would be needed unless you plan on also using a groundplane kit on the antenna. With that the antenna, the radiation foot print might be kind of weird. You don't want your coax radiating but it might. Grounding is important with any antenna. I think that running heavy aluminum ground wire around the perimiter might help but then who knows what the radiation pattern might be. My knowledge of this is limited but it all will be trial and error. It might work great with a little tinkering, good luck and if you deceide to try a stick antenna let us know what the results are. In an apartment building, any indoor rig is going to cause havoc with the neighbors because if interference issues. A set up like this is tricky at best, and this is all that I know to try and help you so, again, good luck.

I too would go with a dipole, it's way cheaper (materials) and would be easier to tune for the frequency you're going to transmit on.
If you already have the other antenna, by all means try it. But I'd recommend the dipole.
