ok I parked my car in the main street of
Broken Hill today and when I got back some one has snaped the bull bar mounted antenna for the CB radio
Now I do not have a spare CB antenna but I have a spare
mobil phone antenna
this one of the white ones
So it has the same connection as the CB radio so can I use that till I get a new CB radio UHF antenna
Thanks

Yes you can use your phone or any other antenna that will screw on to the mount to get some communications. It will not be as efficient as a tuned antenna but you will still get a bit of range. In other words, any wet piece of string will work a bit as we say in the trade.
Don't worry about transmitter damage. All sets are
well protected these days. The don't use it scare only applied to two way radio transmitters in the 1960s.
Is there a DSE of Jaycar stockist in the
Hill? They should have replacement whips.

I have actually used the top wire on a farmers fence to show what can be used for emergency communications. But that was with a different job and it was with much more sophisticated equipment than just a CB radio.
Yes, in an emergency you can use it and very briefly, but the signal will be almost unreadable beyond a few hundred meters, that is if it even gets that far.
A damaged, broken or even just a random length of wire will reflect most if not all of the signal back to the radio. The output circuitry in modern radios can handle some reflection. But not a lot and not for long. You will destroy it if you continue. The radio will then automatically cut back the transmission to hopefully not allow this reflected signal to damage the radio.
Buy a cheapie for the "back seat" and get another for the front.

ok went to local
shop and picked up this antenna nothing fancy I said just want it to work
now put it on went to channel 1 tested it out on local repeater nothing drove into town next to repeater it works
ok that got me stumped went back to
shop no idea
ok last night I went to Google ad did some reading up one site said this type of antenna is not suitable for bull bar use
ok this car was owned by Lachlan Shire before I bought it
now I was looking at the boot and some thing I did not notice 4 small hole in boot wall some one has put a antenna on each side of the rear quarter so off to the
shop bought a bracket and fitted it and yes got the repeater right away
so a word to the wise if you buy one of those antenna s and put on the bull bar and it does not work try relocating it to another part of the car
what annoys me is the people at the
shop said it would not make any difference and they are supposed to know about this type of thing
cheers and thanks for the help

I should add the radio did work but the reception was down and the only way I realized that was the repeater
I know I was able to get it before at
home
if I had not known about the repeater I would have left it not realizing I had a problem

If you cut a piece of wire, any old wire, 310mm long and connect that to the antenna stub or the centre pin of the socket and *insulate* it from the bodywork that will work reasonably
well. Maybe tape it to a piece of wooden dowel and tape the dowel to the bullbar. This antenna, like your original, should be mounted vertically.

Well this is interesting.
We have some varying opinions.
"DON'T DO IT, YOU WILL BLOW YOUR RADIO TO BITS.
A LUMP OF FENCING WIRE WILL ONLY TRANSMIT FROM THE 'ROO BAR TO THE BACK BUMPER.
AN OLD WIRE CLOTHS HANGER WILL WORK JUST FINE.
I think I might just stick to a dedicated aerial.........just in case (;=))
Cheers
