I live a few hundred yards from one of Cary's 3 sites, so I receive them fine. As for Wake County, some of the transmissions drop in mid-sentence or I get the birdie sound from the data talkgroup 28752, which I haven't figured how to lock out. I guess I'll do some further tweaking with the P25 Threshold. Thanks for your info!If your getting 5 bars of signal you dont need an antenna besides the rod antenna. I suspect you are getting a good signal, thats one thing with multiple towers you should be getting good signal.
Simulcast, if you have a better antenna, rule of thumb means it will make any simulcast issues worse. Only thing if you still want one that would help your simulcast reception is a yagi directional antenna pointed towards your nearest tower.
