Review on RG58A/U Coax Cable 3ft Jumper: CB/Ham Radio Connector - Workman CX-3-PL-PL, Made in USA by Jamar Gow

Plug shell too deep for most socket connections. The plug of the cable rests against the base plate of the socket before tightening. This causes an unreliable connection to ground and results in a dramatic increase in SWR. After figuring out why, I checked the connections and found that I could still wiggle the cable even though I was holding the external connector's knurled ring firmly. I had to grind the knurled ring on the cable's outer jacket to keep it from touching the SWR meter or radio jack. It was the only way I could build a strong connection.
