I am at a loss in tuning my CB antenna. I have tried tuning in Te factory one with no results. Bought a 3' one and mounted it on the side pillar between the drivers window and the windshield with no luck. Then I bought a 2' Firestick and replaced the factory one with the Firestick still no luck. Then I tried putting the Firestick on the mount I installed on the side pillar again no luck. I removed all the Dicor around Te factory base to determine if Te ground wire was there, it was. After doing all this I still have lights on the RX/TX side and get the red light warning for the antenna. When I calibrate Te CB and try tuning it, if I touch the base the antenna light goes out.

The CB is a Cobra 29LTD Classic which I bought last fall.

Yes, before anyone ask, I did have the red tip on the Firestick while doing the adjustments.

Are you tuning with SWR meter,and it could be coax cable

I agree, a good SWR meter is necessary to match your radio to an antenna. Cable, the fine wires that make up the braid shielding are tricky to work, just one touching the center conductor wire will create a "red light condition" or high standing wave. If you are not familiar with CB installations, I suggest visiting a CB shop to have them check everything and adjust standing wave. FWIW, the standing wave adjustment on the radio is not a substitute for using a good SWR meter in-line with the antenna.

Sure will help. See if you can find someone that already has one hate to buy one when probably only going to use it once. The SWR on the CB is pretty much like an idiot light on the dash. you got a problem or you don't!!!! :) As i recall Firestick has a good tutorial on how to set the SWR in case you need that. ;)

If you have a CB shop in your area, it is only a few $$ to have them do the adjustment using a SWR unit.

Since I don't know what I'm doing, and it involvesw cutting something off the end of the antenna, I let a CB shop at a truck stop do mine. A man has got to know his limitations.

some light reading

the handbook is one I used to learn electronics
the Anteana one is more than you need but does cover the 27meter range the hams use.

learn enough you can get a real radio.

To be honest I use mine if traveling with someone else to stay in touch. Other use is for traffic reports say going down highway and traffic back up because of accident maybe and have used it to make the decision to get off and go around it. Mine also has the weather service and will alert when there is one can be helpful as well. I think I used it once at J scale but most of the time they never answer. Other than that I set squelch so high someone almost needs be almost next to me before breaking through. Sometimes if bored will listen but seldom actually. My brother and OTR for well over 30 years rarely uses it either because of the foul month stuff and pretty much being useless except maybe in an emergency but with cell phones that becomes less and less of a need. <_<

When traffic comes to a halt out in the boonies, listening to others can guide your decision about detours, etc. Having a radio installed for just obtaining information during such situations is a cheap addition to your traveling vehicle. Otherwise, you are deaf and dumb, and sitting there....wondering, maybe for hours.
