But hhhhhere's a question for the braintrust:

I'm after a (mobile) VHF radio that's common to northern (i.e., the
Yukon,
and Northwest Territories) Canadian truckers- who don't monitor CB bands.

I'm sure, as a sine wave challenged layman, that I can't use the same
antenna and coax as my CB?

In principle, you could combine the CB output (27 MHz) with the VHF
radio output (up above the 2-meter band) using a diplexer, and feed
the result down a single coax.

At the antenna end, you'd have a couple of choices. You can use
another diplexer to split out the HF and VHF signals, and feed them to
two separate antennas. Or, you might be able to find a single CB-type
antenna which is also capable of matching up well enough on these VHF
frequencies to work tolerably well.

The chances are very poor that a randomly-selected CB antenna would
give you a tolerable SWR on the 160-or-so-MHz VHF band... and if it
did, there's no telling what its vertical radiation pattern would look
like. An antenna intended for these two bands would probably have to
be custom designed - I can think of a couple of possible ways to do
it. Such a dualband antenna would almost certainly be a compromise
antenna on both bands - it wouldn't work as well as separate antennas
designed for best operation on a single band each.

Commercial HF/VHF diplexers run somewhere around $80, last time I
looked. You'd probably find it less expensive in the end to just run
a second coax and put up a second (VHF-only) whip antenna.

Trust me. he has no clues as to what you just said.

Not a ****in clue, Richard, and not ashamed to admit it.

What ever it is, I can learn it, teach it to myself.

I'm not afraid to ask questions, like the one that set you off on this
rant, and I'm not afraid to ask for help.

It's -easy- when you're a man.

This fool wants to run a vhf radio in Canada just to talk to Canadian
truckers.

That's all in your mind, a baseless lie you repeat with no evidence.

I've stated, clearly and concisely, what the radio is for.

It's your projection of your own actions that leaves you apoplectic.

I'm sure when you're on the radio that you irritate working drivers for
miles, till they won't respond to you anymore, and then you key the mike on
pathetic country music.

Since -you- do that, -everybody- must...

He thinks those radios can be bought and used just like a
CB.

Well, sort of, yes.

My CB is illegal too... ;-)

And no one gives a -damn-.

My 78 Suburban has a ten meter radio and a boat radio in it, neither with
a license, for twenty years now.

As I have operated radios on 47mhz, held a 2nd class fcc license, I
think I know a lot more than he does.

No one cares.

Still waiting for you, 10 posts later, to provide some actual information
instead of the screeching and wailing.
