installed a galaxy dx 48t and have some ?s

Is the mount installed with the plastic washer on top?

 

Put a cheap radio in the truck and stop using your 48T until you correct the antenna problem. Unless supporting CB shops with expensive repair work is your goal. 230 watts is excessively high power for that model anyway, and this is when running a low SWR, a good antenna system. No doubt your shop has clipped all limiting out of it, not the best idea to begin with. Honestly you amaze me running a high dollar radio and asking the questions you have after stating "I haven't tried trimming the antenna yet.". Simply astounding. Word to the wise: run cheap low power radios while working out your antenna problems. Only when you know it is good do you put the big radio back in and run it.

Simple common sense.

 

Usually the whip that comes with the antenna needs quite a bit of trimming. Check swr on ch 20 on each of your bands B-C-D-E-F. See where the swr is the lowest that will tell you how far it's off.

 

"I wasn't trying to make anyone mad."

I assume you mean me but that would be incorrect. No emotion involved at all. Simply trying to stop you from doing great harm to your 48T. For me to be angry it would have to be costing me something. Not possible since it is not my radio in danger. RR has a good suggestion assuming you turn the carrier down as low as it will go and minimize key up time while making measurements to reduce overheating in your 48T's final stage. The reason being he is probably correct that the stinger is so far off a 40 channel radio may not provide the information you need to see where the antenna is resonant so you can know which way and how far to go to get it within the 40 CB channels.

 

I would trim 1/8" off the whip and see where it falls. I am asuuming you have the whip all the way down now. the swr's now arent bad but me personally I would trim a hair off the whip and see if they come down a little more. just my .02
