CB Radio re SWR question...ANSWERED (update)
Back in 2003, MH came with optional CB antenna installed (no ground plane model). I installed a Cobra 29 LTD Classic radio, and as per usual didn't bother to read the manual. It never had more than ...

Thanks for all the replies, kinda makes me feel like I'm back in school.
Let me first say that the SWR meter that I'm using is NOT high-quality. It's the one that's built-in, on the front panel of the radio. It's rectilinear with vertical needle. It's small, .410" x 1.185". It has 3 horizontal scales; SWR, RF, SIG. The "green" of the SWR scale goes to 3, and the remainder is "red".
In the off position the needle is at .062" less than the start of the "green", which is 1. On the S/RF mode, when main switch is turned ON the needle does not move, but you can make it start moving by cranking up the RF Gain knob past about 65%.
OK, I realize that the above info might not mean anything, but I find it odd that the needle goes below 1 (in SWR mode).
Anyway, after reading all your replies up to this point, I will probably decide to experiment further, like adjusting the antenna to 1.5 SWR on channel 14, and then do some more field testing.
Also, I will now Google KOBG, and see about learning some basics on antenna installation and technical design points.
I'll report back when I have something. Thanks again
