Yes you can buy coax swithches to switch between 2-3 antennas if you really want. (Think of garden hose with a two way switch). They isolate one antenna while using the other.

But for everyday use this is overkill for UHF CB. I think GME offer a "plug and play" system where you can screw on an extra section or different whip to the antenna to increase gain from say 3db to 6db.

Some truckies will have UHF, 27mhz, mobile phone and company radios + scanners etc.

Some do co-phase two antennas to give a better radiation pattern which is otherwise affected by the mass of the truck. Again this is complex and not worth the effort on your Triton.

So.... those B&S utes with 5,6 or 7 aerials are really just trying to get the best range from their radio, mobile phone and scanner?!! and here's me thinking they might have been posers :lol: :lol:

Does anyone know if the GME TX 3100 and TX 3340 have the provision to plug in a remote speaker as I looking at one of these and are concerned that if I tuck it away somewhere out of sight we wont be able to hear it very well . :? :?:

Also what are peoples thoughts on the Unidens as the local ARB blokes reckon to stay away from them :?

Was told the same thing sam by TJM.

Installed this Oricom UHF050 yesterday. Happy so far, seems like good solid contruction with a 3 year warranty. Radio, aerial and aerial bracket for under the price of a GME but with more features.

I have had a Uniden UH-090 for about 8 years and in three different vehicles. Units are still being sold. Never had a problem. This unit has dual banding and operates on 40ch UHF as well as 40ch AM which is the old CB radio channel from 20 years ago. A lot of truckies still operate this AM frequency and I need it as my customers have the AM band on their loaders that fill the semi's. I need to contact these loaders when I am entering their work zone's. Just swap aerials and the coax lead between HF(AM) or UHF and away I go. Have noticed that I do not get the range that the newer radios are getting, I can hear them but they cant hear me sort of thing, but not worth the cost of getting a new radio for the amount of time that I use it in UHF mode. This radio is a 3/4 Din unit and should have been a full din to get the best range I suppose. As I said my radio is 8 odd years old though and never had a problem so I'm happy with Uniden. Wouldn't trust ARB though as they will flog their own gear. Talk to a decent communication company that sells all makes and see what comes back. Thats what I did 8 years ago and they recommended Uniden. Then bought the unit over the internet cheaper than the comms company could supply it. The salesman said go for it.

Couple of B&S units running around were I live, and not all their aerials are hooked. Just posses :roll: :lol:

I had my heart set on a GME, but TJM managed to sell me on this unit. It is supposed to be as good as GME only with more features for the money. I had never heard of the brand but 3 years warranty sounds good. The unit cost me $219. The GME unit is around $430, so for the cost of a GME I got the radio and a 4.5dba aerial. The unit certainly looks the goods. The body is full metal and all the connections are screw in type, not phone type.

GME, Uniden, Oricom they are all OK radios for yor 4x4.

But as noted in another thread, UHF is moving to 80ch (12.5khz spacing instead of 25khz). So getting an Icom IC400 pro where you can program the frequencies and power :D will be worth the extra $$ to futureproof your radio. Apart from that, they are military spec quality - bullet proof.

Ha, have you guessed that I have one yet... :o

When is this change meant to be happening and does it mean radio's like GME, Uniden and Oricom will be redundent or will you be able to get them upgraded :? :?:

Not sure that the Aust Comms and Media Auth'y (ACMA) has put any changes in law yet - they are considering proposals to free up space in the 400Mhz band. But if they do, existing CB's will continue to work on the existing 40 ch, but simply wont have access to the other 40 as they will be positioned between the existing channels.

I cannot imagine every person with a CB replacing it overnight so the change will be long term and people will continue to use ch40 etc for highway.

This is where i put mt TX3100, can see it clearly when driving and mounted a extension speaker down in front of the gear leaver. The only aerial i use is a Polar 6.5db spring base, I put one on my last Pajero and it was there for over 10 years and was still working well when i sold it :D

eBay have the Oricom UHF050 for $180 - free delivery. Not a bad deal.

CD the short answer to that is NO, but that is not quite truthful. You can have 2 identical antennas wired with what we call a harness and used by ham radio operators. Usually these are 2 yagi type antenna (multi element beams) used for Satellite and moon bounce operations 2 specialized modes used by hams. Definitely not suitable for mobile operations.

This thread has been very useful for my CB install yesterday - thanks (not quite finished yet and will do write up for MN GLX-R Auto when done) - but - a warning, the front of the rear console sits on top of the back end of the front console and it needs to removed but pulling it straight up as there are two vertical posts/clips to pop out (one on each side). I tried to remove mine by lifting the back of the rear console and pulling up and back - snapped the posts (bugger). Also, sitting on top of the transmission tunnel and under the dash is the airbag control module (not the bluetooth unit as in other models) so be careful.

not sure of how many other people used the Gromit on the Drivers side. But i replaced my Whip antenna with a fibreglass one and had a hard time putting the gromit back in. After 10 mins of frustrated swearing because of the damn small space my hand was in, my old man shook his head and dissappeared into the shed came back with a little white tub of Vaseline. i put a small amount on the sides and it just popped in.. Damn old Dog and his old tricks.. he coulda told me 2 cars ago! :evil: :evil: .

in hindsight i should have used the other bigger cable entry its much easier and i could have just cut and connected a new coax section but im a believer in less joints the better
i spose it goes for most grommits that dont quite want to fit back in the original hole. but a small amount of Vaseline Jelly is the bomb.

It is one of lifes lessons i have learned if u cant force it in, just use more lube :lol:

Washing up detergent (sometimes with a little water) works well too and when it dries it helps seal things too. (us old dogs don't need to learn new tricks - the old ones suit us just fine :lol: )

I think it has to rotate - the hole has a notch/ key in it. Not that I've taken mine out. Did you mean 24? Twice the volts the lighter will have

T-bags, here are a couple of threads which discuss power to the UHF:

http://www.newtriton.net/phpbb/viewtopic.php?f=51&t=4630

I think the consensus is that taking power from the cigarette lighter isn't the ideal choice.
