Hi,
If I'm not able to set the SWR in the trucks that I drive will it
hurt the radio or just give me decreased range?




My problem is that I'll be moving from truck to truck so I wont have
time to set the SWR correctly. Most of our trucks have factory
installed double antenna's which I'm not too thrilled about.




Thanks for your input. I dont want a "big" radio. I just want a quality
radio. I'm looking at either the PC68ELITE or the PC78ELITE both from
Uniden. I had a PC68 about ten years ago that I had tweeked and it was a
great unit. I was just on a CB site and I seen that they sell a box that
lets you set the SWR from your seat without touching the antenna. The box
is plugged inbetween your radio and antenna and then you just use your SWR
meter plus the knobs on the box to adjust to the desired level that you
want. Are these things any good or are they a gimmick?
Thanks,
Driver42

John,

I just was reading about this radio.
http://www.galaxyradios.com/cb/959.html
says it has an "Automatic SWR Circuit (no complicated calibration
procedure)" Does that mean the circuit sets the SWR automatically?
Thanks for your help

No. It means that it will read the SWR ratio without you having to
manually calibrate the meter. It does not correct the problem if there
is one.

If you move the radio from location to location just check the
reading. If it's 2:1 or lower don't worry about it.

Thanks,
I have an SWR meter from radio shack that I've used in the past. I know how
to use it. My problem is that I'll be in a different truck everyday and
wont be able to set the SWR the way I want to. On Monday I'm gonna call the
cb shop that I saw online and ask them about the SWR match box. Below is a
cut and paste of this product. Let me know if this will set the SWR without
having to mess with the antenna's.

"Don't "Live with" High SWR Readings! This Matcher will tune your SWR very
low, simply insert inline between radio & Antenna. Has 2 Adjustment knobs.
Perfect for Radios with wide channel coverage, indoor antennas, non-tunable
mobile antennas, or for using 10 thru 12 meters off 1 antenna. Handles 80w
pep. Requires either an SWR meter built into radio, or an optional SWR
meter between Radio & Matcher."

Don't be anal about SWR. If you have an SWR of between 1.5 to 2,
don't worry about it. If you must have 1.0:1 on every channel,
you'll need a tuner to "fix" it. SWR is a ratio of impedance.
It is only one of a multitude of important parameters. I like high
field strength. It shows you how well your antenna is radiating.

If you move the radio from location to location just check the
reading. If it's 2:1 or lower don't worry about it.

This is a line flattener. They can be problematic in that one of the
knobs can be bumped and give you an abnormally high SWR reading.
Much higher than the antenna itself.

You also will double the possibility of a loose coax connector, and
don't forget that moving the setup will require more time and care.

.....oh brother, more voodoo CB terminology.

If the line has standing waves on it then it isn't flat, and no
matching device on the radio end can reduce or eliminate the line-load
mismatch causing the standing waves. The only "line flattener" is a
LOAD impedance that matches the LINE impedance. You can't do that at
the radio.


They can be problematic in that one of the
knobs can be bumped and give you an abnormally high SWR reading.

Or the antenna can hit a tree and fall off, or the coax could get
jammed in the door, or the radio's power leads could be accidently
shorted by a sharp edge under the dash.......

don't forget that moving the setup will require more time and care.


Oh, the turmoil of it all! So why even bother using the CB in the
first place if there's going to be the possibility of a problem? If
you want to discourage the guy from using a matching device then at
least give him some -valid- reasons. Like, you probably won't notice
any difference if the SWR is 3:1 and not 1:1, or that the importance
of SWR is moot when compared to field strength, or that any matching
device isn't going to accomplish squat with a cigarette-lighter radio
and a mag-mount antenna.

This isn't exactly a performance rig, and the fact is that SWR isn't
going to tell you anything -- if you manage to get it to 1:1 you'll
get a warm-fuzzy, but that's about it. Just plug it in and talk. If
someone hears you, great. If they don't, there's probably nothing you
can do short of a full and proper install that will get you heard.

Yes, such a device will allow you to adjust the swr under adverse conditions
and is good to have, at least if the swr is high you can adjust it down and use
the darn radio--now that beats sitting there with a darn useless setup!!!

Since you can voice your concerns, and have awareness that swr is important--I
take it for granted you have the common sense how to read instructions properly
and use it--if not, someone which knows how should be consulted--some of those
truckers are savvy to swr and such, if not, large truck stops always have a
radio shop close, or usually do...

So, I'd give a thumbs up to the matchbox (use in combination with your SWR
meter)... there is some "insertion loss" from the matchbox, and a bit of a
power loss, this is almost always negligible and not enough to worry
about--just make sure you don't run a linear into it, that match box says it
will handle 80 watts pep (that is only about 55 watts rms) so don't burn it up
AND the radio/linear!!! (you could use a 50 watt linear, or less, with it
safely, or have BIG finals in your cb which puts out 50 or less watts.)

Hope all of this helps and I didn't get too "wordy."

The other poster is correct, NOTHING will set the SWR automatically for you,
that is always an adjustment of the antenna and/or feedline, sorry about that!
