need to chat with some of you CB radio Guru's about why my CB takes the meter to red and turns on the antenna light, with any antenna I try, new radio & mike (twice), grounded cab to frame, moved antenna, and all the etc's I can think up.

Antenna length not adjusted right. Length is critical, 1/8th inch off can mess it up. Talk to the people at store where you bought antenna. SWR meter is needed. They can sell you a SWR meter for around 30 bucks & explain how to use it, do it themselves, or refer you to someone locally that can do it.

Connect transmitter to a 50 ohm dummy load. If the warning light STILL come on you have an internal radio problem. If ok on the dummy, you have cable or antenna isssues.

What would the 50 ohm dummy load be? I assume connected to the antenna outlet.

Thank you. I thought your advice was the cure. SWR meter read below 2,but when I disconnected the meter, the radio meter went to the 3+ again and turned on the antenna warning light. So I went to another truck, new antenna lead, different radio, or the same radio-same result-runs the radio swr meter into the 3+ zone. Changed to a 48" antenna and same result.

A Dummy Load is a piece of test equipment that is used when testing/repairing transmitters. It is connected to the antenna connection of the transceiver.
