I am trying to find an antenna for my old PRO-92, (collecting dust atm), BNC antenna mount, that will work reasonably well to listen to nearby CHP frequencies, within a few miles, in 42Mhz band. Also maybe listening to VHF aircraft band, from SFO Airport, about two miles away, I think they are on 700Mhz band.
I read just yesterday, from a search on google, about a guy that was using an antenna that they got from Amazon, he called it the Chinese antenna, that worked better than a lot of others, and for the life of me, can't find the article. He mentioned look for an antenna that was tuned for 42 Mhz but it did include VHF frequency range too. I think he mentioned it was about 40"?
I wondered if an 11 meter antenna would work possibly.
The CHP channels that have both mobile and base transmissions are all in the 42 Mhz band, and are rebroadcast from dispatch.
42.080 – 48.940 range. (42.080 42.620 42.120 44.800 42.420 44.940 42.920 42.440 42.500 42.600 42.160), which covers all the 11 bay area counties, and these are actually the only 11 frequencies that I need to listen on for CHP.
I would also be listening to 3 counties, (Alameda, Contra Costa and Dublin Counties), when visiting my friends in San Ramon every week.
I listen to all fire on my SDS-100 for all the counties, but all their low band and other bands are on the P-25 digital system.
The main freeway here at home Hwy 101, is 1 mile away and is a main corridor for CHP from San Francisco, (6 miles north), and Redwood City, (14 miles south) of me.
I have an SDS-100 with a Remtronics REM-820S, that picks up CHP infrequently, on the 700 Mhz band from 34 miles away in Dublin, Alameda County), but it is only rare anad useless since both bas and mobile are not on those together, and I don't hear any sporatic calls on my side of the bay from CHP at all on the 700 Mhz band. The CHP mobile units transmit on 42 Mhz band to the cars, and the base transmits 42Mhz to the car/mobile, and both are re broadcast through dispatch on 42 MHZ. The frequencies to scan for base and mobile together are all in 42Mhz band.
I appreciate any help if at all possible. Hopefully to be scanning low band soon. ☺
