Thanks for the info. One question does the 800 mhz have the correct connector or is there more pieces to purchase if so what would they be? Have u ever heard or used the Diamond SRH-789? Sorry if this question is simple I'm new to this. Thanks
I have tried the
SRH-789 on my Home Patrol. It's better than the stock antenna, but IMHO, there's other antennas I would use over it. I connected the 789 to my HP-1, which has the Extreme upgrade, then used the RF Power Plot choice under the Analyze systems menu to compare reception using the SRH-789 (at the suggested lengths marked on it, as well as adjusting it slightly longer and shorter) with several other antennas.
The 789 is an acceptable choice, if you are mainly interested in one band. It does have the advantage of coming in an SMA version, and has the swivel base, so no right angle adapter needed. But there are better options from what I saw, if reception strength is your concern. The Diamond
RH77CA was better on Vhf-high and Uhf. (A similar antenna, sold under the name of the "
Gainer", is equivalent to the RH771. I have one of those as well. No real difference between it & the RH77CA.) The Radio Shack
800 MHz antenna is what I'm mostly using, when I'm not connecting the HP to an external (roof mounted) antenna. It has better reception on the multiple trunked systems in the area than the 789 or the other two antennas (or the original), good Uhf reception, and acceptable Vhf-high. If your primary interest is 800Mhz, then the R/S antenna is your best bet. For Vhf-high, one of the Diamond antennas, or something else more tailored for that frequency band, would be better. Be sure to check out the posts in the Antennas
forum for other suggestions.
For any antenna but the SMA version of the SRH-789, you would need an adapter, as Larry already noted. I'm using the SMA male to BNC female adapter (item 0292 on
this page). It's low profile, and the black color matches up with the Home Patrol's case. Then, you also need a right angle BNC adapter; you can pick this
one up at Radio Shack. (You can find similar adapters elsewhere on the web as well.)
