YES you must have the power plug for ground at a minimum. The antenna must also be working properly. The out side of the CB case doesn't HAVE to be grounded but it is better over all if it is.

Cobra 19 new does not have good reception or out put

Hi, my name is John. Welcome to FixYa. Check your antenna, make sure it is grounded good to the body of the vehicle, and that nothing is blocking it. Turn the SQUELCH all the way to the left. Have your SWR checked. You can get it done at Radio Shack for free, or any roadside CB shack. Thanks for choosing FixYa...John

CB transmission

Hello 64driver,

Make sure the radio is grounded properly and that the SWR is around 1.2:1, 1.3:1 is good but try to get it to 1.2:1. Also take a power output reading while keying the mic. To do this with your power meter put it in-line with the CB and your antenna and key the mic you should get about 4 to 5 watts PEP. If this is the case your unit is putting out the proper power level, if not have the power amplifier checked by a qualified repair shop.

I hope this helps
