Has anybody done this yet?

[Robotech2112]

Has anybody used the G4, G5 amplifier / charger's external antenna jack in a mobile to coaxially connect a body mount antenna; NMO, TLM, etc? If so, do tell. Pic too if you want. I am told the receive is great and an external ant. is not needed in a lot of cases, but I want to anyway. Tell me about your experience, if you wish.
I am thinking of using this guy on a TLM.

If memory serves me correctly, the desktop charger/base external antenna only connects to the secondary band. The 700/800 band always uses the external stubby antenna.
Unless they made changes since i had one.

I was wrong. LOL

Ok thanks for that info.

My experience is at home. I actually use a 13.5 db gain Yagi antenna with my G5 and speaker amplifier base. I use it to receive a system that is over 40 miles away. I get 2 to 3 bars on the G5 from the factory antenna on the pager, but get all 4 or full scale with the Yagi connected to the base. This is 800mhz P25 system.

Thank you for that input.

Do you have the G4/G5 already? It may not be worth messing with external antennas, unless you're in a really marginal coverage situation. The 7/800MHz receiver is so good that I just clip mine on the visor above my head when I'm driving (which seems it shouldn't work as well as it does, under the metal roof), and then clip it on my belt when I jump out, without needing to disconnect an external antenna and connect a portable one.

I just received mine today haven't had a chance to use it yet.
I am going to test coverage in my home county however my adjacent county is going to P25 within the next 6 months . I want to be able to listen to both counties regardless of which county I am sitting in in a mobile.

I allready have the antennas from a previous set up.

Thank you for your reply and your input, I appreciate it.

Perhaps you are aware of this already, but in case not the Unication G4/G5 pagers can only monitor one trunked P25 system at a time. You can put up to 16 conventional channels in a scan list, but you can only scan one such list at a time. The radio won't scan a conventional scan list and also a P25 trunk system at the same time.

Yes, I am aware. I will listen to either a conv system in 1 county or the P25 in the other county, but only one at a time. When the county with the conv system goes to P25 the same rules apply, one system at a time. Thanks.

I regularly receive P25 sites from 40-45 miles away with the stock G4 antenna, even while mobile in the cars cupholder.

 

[Robotech2112]

That is incredible.

Using a 13 dBi Yagi, I'm getting excellent decode from a 700 MHz phase 1 system whose tower is 75 miles away. The signal is very weak, but the G5 does a great job with it. The audio sounds better than it does on my local system. Using an adapter I just attach the coax directly to the SMA connector.
