Question about Cobra 19 DX IV CB Radio
To your answer on my first question, the power meter says it is putting out all 4 watts. I even bought another cobra 19, hooked it up and it sounded exactly the same, garbled and unreadable. The SWR is 1.3 and the 4' firestick is not tunable. There is something else going on here. The unit is grounded to the body, power lead directly to battery. top of antenna is even with the top of vehicle but out on front bumper so the top half of antenna is clear of obstuction for several feet. Are these CB units just totally chinese trash?
No, those radios are good radios. I have one just for setting swrs on antennas.
First, I went back and read your last question. You said you have a nylon washer on top AND bottom? Did you mean one under on the top and bottom side of the antenna mount? You only need theone on the top of the antenna mount, which stops the antenna itself from being grounded out. Having one on the underside stops the outter part of the stud, the one that touches the outer screw on part of the coax from being grounded. Without that getting a good ground, you have no groundplane, which will cut your tx/rx to a max of 2 miles. Also, how close is the two setups. Many times, if two vehicles are setting next to each other, you will not receive or transmit properly, just get a nasty garbled with a hint of a squeal.
