Newbee trying to improve indoor Police Scanner reception on P25 Phase 2 Simulcast weak signal situation.
Same boat here. Indoor only antenna at this time. FMPA (tcp out ) with DSDPlus does a good job for what I listen too. FMPA works better with weaker signals than FMP24.
If you know linux, try OP25. It does good on the simulcast site I listen to also.
I have a 1/4 ground plane antenna cut to proper calculated length and I also have used a small Tram multi frequency mag mount antenna mounted to a 16" metal pizza pan that works pretty good too but never quite satisfied with the reception.
Those antennas are omni directional. Meaning they receive from all directions. I made a moxon antenna tuned for 770mhz. That antenna is directional like a yagi sort of. https://forums.radioreference.com/threads/772-mhz-moxon-antenna-project.379514/
seems like the antenna with the weaker signal performs better on the simulcast tower I'm looking at
It could be that the weaker antenna (less db gain) is not pulling in much from other towers and is sort of attenuating the signal.
