What would cause the ant light on a stock cobra 29 ltd to come on when i key the mike. And if it is an antenna problem what do you think would be the best for this radio,I am an over the road truck driver so I need it to work well.thanks for your help.

I agree with mr cb that cobra radios are the primary work horse for otr drivers. when it comes to antennas that will be an opinion that is totally up to you but some good recommendations would be a Wilson trucker type of antenna but there are others that will work as well. How well any antenna works for the most part depends on where you mount it,resonance (tuning) and radiation efficiency. The standard that all antennas are measured against is the almighty whip 1/4 wave long @ 102" made of stainless steel and will handle 10,000 watts of power all day every day but in your case there is a catch 22 this type of antenna is not recommended due to the fact that it is 8' 7,1/4" long and i am under the impression that this antenna needs to fit a big rig truck. The situation you are faced with on height limits the wilson 5k or 2k with a good tune would be the best choices for you in my humble opinion. hope this helps.

Hello, My name is John, Hope I can assist you...The light that comes on when you key the mike is a RF indicator, meaning you have RF power, meaning your unit is fine for talking if it is the TX light, some lights will blink as you talk. Have your SWR checked at a CB shack, or Radio Shack, etc. Enjoy.Cobras are great radios.....Hope this was helpful........
