How effective would a UHF transmitting antenna be if It were to mounted in the attic ??? The roof is made of tile.

What kind of tile? If it's concrete tile, I would think you'd get a sgnificant amount of signal absorbed before it left your attic. If it's plastic tile, that shouldn't be a problem. As I wrote in another thread, reflective foil insulation will also be a problem.

Yes, the tile is concrete. I was thinking of mounting the antenna in the second story attic infront of a wooded air vent. I'm trying to get away with not having to mount the antenna outside. But, I guess I'm not going to have much of a choice. BTW this will be used for a low powered Motorola Desktrac UHF repeater with an attached MRTI.

What is the repeater being used for? We really need to know that in order to determine if a given mounting location will be adequate. Some other things likes like duplexer, feedline, antenna type, power, etc would be helpful.

This will be a local repeater with a Motorola MRTI 1000 attached, approx. 45 watts, feed line is RG-213, with a small duplexer mounted by the desktrac. The antenna is a 1/4 wave ground plain, and the frequency is UHF.

Local is very broad. Where, how far? Are you even licensed to be doing this?

Sounds like he wants a far reaching cordless phone!

What service is this going to be licensed under?
