UHF Cb in Australia is in the range of 476.425 - 477.400 MHz.
Sorry, i was thinking i was posting in an Australin ng.

So i need an antenna to cover 144-148, 430-440 and 476.425-477.400MHz

Thanks.

Gary,
I'm not familiar with UHFCB at all, what frequency range is it in?

Gary,
For what it's worth, take a look at some of the "Comet" mobile 'dual
band' antennas. They advertise as being broadbanded and are to some
extent (how much, I don't know). I've had no reason to try the
'UHFCB' frequencies, but I do know that at least one of 'Comet's dual-
band antennas is fairly broadbanded on 2 meters/150 Mhz. Can't
measure on the UHF portions so can't say one way or the other.

And also keep in mind that "FWIW" thingy! As in, don't take my word
for it.

=======================================
UHFcb in Oz-land is highly likely similar to PMR446 in Europe and FRS
in the USA.

PMR446 are 8 RF channels with 12.5 kHz spacing starting at 446.0025
MHz . That means using a Ham radio it must have the capability to be
set at 2.5 kHz channel spacing and few if any ham transceivers have
that. Also, the deviation is set at a low 1.5 KHz.

So I wonder how UHFcb is operated in Australia ........would a Ham radio
with extended range be usable ?

They certainly are, i'm using a couple at the moment. Our 2 Mtr and 70cm and
UHF CB are all 25KHz spacings.
There is talk of changing the UHFcb to 12.5 Kc to get 80 channels instead of
40 but i don't see how this will work as there will still be thousands of 40
channel radios out there with standard deviation splattering all over the
newer narrower radios.

As for the pmr446 band, you need a radio that will do 12.5kHz not 2.5 which
are available here and i would guess many other countries. From what i read
the band starts at 446.0 and goes to 446.1, thus 446.012.5 - ch1, 446.025 -
ch2, 446.037.5 - ch3 446.050 - ch4 etc. The deviation for that would be
around 8kHz and for 25KHz would be around 12. i think, not 100% but i'm sure
it's something like that over here.

Anyhow, i still need an antenna lol.

That depends on the laws of your country. In the US it would have to
be type accepted by the FCC and ham radio would not qualify.
