    Ok now we are getting somewere. You have reached a perfect swr on 20 and 40. . Still a little high on 1 but that is easily fixable. Just raise the whip slightly. go in either of an inch increments at a time. Check SWR each time you adjust the antenna whip.

    The main thing is that the SWR is safe. I would not worry too much about the light as long as your swr is less then 2. Perfer it to be around 1.5 or less but less then 2 will not be damaging to the final in the radio.

    I will make the new changes you suggested tomorrow. I talked with Cobra today and the Antenna Warning light was a false positive. He first told me that I would have to send the radio in to have it adjusted, then he offered to send me the directions on how to adjust it my self.

    I made the adjustment to the radio and no more Antenna Warning. If anyone would like the nice PDF file with photos and very simple directions to fix this send me a PM and I would be glad to send it to you. This will work on the 29 LTD too, maybe some other Cobra 29's too.

    Thank you folks for the help here.

    Made more adjustments today and all SWR readings are down around 1 or on the bottom of the scale.

    Thank you all for the help here

    To the folks who said it could not be the mic. I disagree, I had gone through the same motions as hdrenegade. I finally stopped at a cb shop to get it checked out. The mic had a broken wire inside the connector to the cb. It was touching another wire and when you keyed up. It gave the red light antenna warning.

    I did not say it was his problem and only suggested the possibility. Glad to hear you got it fixed.

    I don't know if someone has already answered you but I have the same CB and HAD the same problem. Here is the solution.

    Run your coax out to a mirror mount for the antenna and get one of those $20 adjustable antennas from a truck stop.. It's thick and black but at the top it has a thin antenna that can slide in and out and tightens down with a hex wrench. Solved the problem and the SWR's are perfectly calibrated.

    Tez,

    I called Cobra, and the fix for mine was an internal adjustment. they sent me the PDF file on how to fix the issue. Thank you for the help.

    05 electraglide classic, Black Cherry, currently runnings andrews 26s, SE pro tuner, Stage 1 filter and high flow intake manifold, The older SE slip ons (the ones that actually make a little noise and make actual power, Updated high flow oil pump, Sundowner seat. Have 95 cylinders and SE flat top pistons waiting along with the better raised intake deck 96 heads. It should be ready for break in sometime next week. Then it goes for final dyno tuning. I am hoping to reach that 100/100 area with it. Next winter it is getting all the paint work removed and freshened up with a fresh black cherry job minus the pin stripes, then going to find some smaller passing lights and update the rear turn signal setup a little and remove the rails. I am also contimplating exhaust changes, Possibly a Fullsac setup or find away to retro one of the newer 2-1-2 aftermarket setups onto it.

    I am also thinking of possibly a cam swap at the time of the 95 install. I really like the 26s but they fall flat too quickly. They pull great through the mid range but fall off more then I care for on top.

    I have no clue why I am doing the 95 in the first place. As it sits it will leave rubber on a hard roll on and it will do it through 3 gears.

    Sounds like a very nice Ride Rat.

    I am getting 115hp and 120tq with mine and with the Thunder Max Tuner I never have to go back on a Dyno again. Roll on Power Rocks!!

    You might take a look at Bad Dad if want to change the rear around a little. Not sure if you have ever looked at Mean City Cycles or not, but he is my seat guy and uses a lot of Bad Dad after market parts on his Road Glide. He also does a fe parts from Paul Yaffey too.

    I do love to ride when I can, and I am less then an hour from the Great Smokey Mtns and less then 10 minutes from getting on the Blue Ridge Parkway too.
