hmm 3 cavities may should work ok 2 on tx one on Rx
might be able to get about 60 db isolation 6 cavities 3 rx 3 tx u could obtain
100db isolation which will greatly improve the repeater operations

Kevin,
Thanks for all the info. The Mastr Pro's are mobiles. I really don't see me
using those for the repeater. As I said, I think my best bet as things stand
right now is to use the Mocom's.
As for a controller, I'm looking at the NHRC mainly due to price, at least to
start. Not sure If I'll tackle the kit form or the assembled/tested (most
likely the latter) but I'm almost certain I'll go with one of these.
Thanks for the antenna suggestions. I'm going to try to go with seperate
antennas to avoid the $$$ of duplexers, but this will depend a lot on the
antenna structure. For example, if I have to go with a water tower, I'll need
to use a single antenna. But if I have vertical tower space, I'll be able to
go with two antennas. One question though: what are your thoughts on the
number of cavities in the duplexer? For example, a 6-cavity vs. a 3-cavity?
I know the 6 will cost more and provide more isolation, but at what point
would I need to decide which one?
Again, thanks!
73,
Jeff, W9SAR
