I have a GME tx3100 mounted in front of the transfer selector in my 2006 Patrol but don't like where it is or the sound of it. I also have an unused GME tx3520 with the wireless remote and a Uniden UH400sx in my Triton with the RM100 remote mic which has been a pleasure to use. I want to de-clutter the dash a bit. Any advice on which is the better unit or where to mount would be appreciated

Do you have any switches mounted in the centre console opposite to the handbrake? If not I have seen some people mount it in there....I use the GME TX3540S and all the buttons are on the hand piece so my unit is hidden under the console and I have a RJ45 plug mounted in the dash for the hand piece. Personal choice really on where you want it...

I have the Gme Tx3540 mounted under/behind the glovebox and the hand piece connects to the socket on the console.

Hi guys, can anyone tell me what is the best antenna to use I have a pic of my current one I will be crossing the Simpson Desert in July and just need to be sure. Thanks44839

Thanks guys. Wish I had a fully remote mic on the GME's like yours. The Uniden does but its a bigger unit so back in the Triton it goes. Ended up mounting the tx3520 under the dash with the face unit next to my leg and the press to talk on the steering wheel and a fairly big external speaker next to the cup holders. I'll post a pic......overlook the grubby interior, just got back from a little trip :-)

The original uhf was mounted where the subwoofer gain control (with the red light) now resides

This pic should explain which antenna u should get. For Simpson desert I would say a high gain antenna.

Your not wrong about the grubby interior, usually only see mess like that in a GQ. lol

Depends what you call high gain.

The Simpson is a significant amount of dune travel IE the vehicle is pointing at the moon or the dirt 50 metres in front therefore so is your antenna radiation lobe.

I would def not recommend anything higher than 6 dBi and 4.5 dBi would be close to ideal

8 or 9 dBi co-linears etc would be fairly problematic and cause comms issues unless you are both on top of a dune

She's looking smick again now :) very rare that the cup holders are empty lol

I've nearly always had a 6 dBi gain antenna and travel the remote beaches, dunes of NW/W Tassie and happy with the results. I'm also no expert !! but do believe it matters where it's mounted

Stupid question ET. Could you run both a hi and low or mid DB antenna together? So you got the best of both? I'm assuming not as if you could everyone would do it....

The short answer is no, at least not to any advantage for what you are after... you would be more than halving your power for starters.

The long answer is you can deliberately run two antennas for an apparent gain but it is directional and very very specialised and is called co-phasing.
It is used to produce specific radiation patterns that would be terrible for a most 4WDers.

If the antennas aren't co-phased but still coupled the radiation patterns would be very unpredictable and vary with frequency versus distance apart if they are on the same plane.

Thought it wouldn't work. Just didn't know why...
Thanks.

run 2 antennas....just use one of these ...instead of a triple , get a double one ...switch over when you want to..there is another connection on the other side that goes to the set

Oo where is that one from ? I have 3 bases on my bar but only have a 2 way splitter

Here is a twin.
