I recently tuned my CB stuff and found that my SWR was super high. I built a new mount and tightened stuff here and there, that brought SWR down to a safe level. Then I fine tuned the antenna to even it out on all channels, I cut the cover and moved a couple of turns of wire up (just like on the firestik site) thats when a funny thing happened, the ANT light started coming on on channels above 13. I bought a new fire stik antenna saturday but that made it worse (now it's on all channels), the SWR is nice and low but the ANT light still comes on. I can send/recieve well most of the time, some times it fades in and out.
