onelinkmore UHF Female to Female Coupler CB Radio Adapter Joiner Coax Connector SO239 PL259 UHF VHF Antenna 4 Hole Flange Panel Mount Adapter Pack of 2

Used to transition through the firewall...works just fine

works

well made and solid mount

Product is well constructed and functions the way it should. Used to couple two fifty foot runs of cable. Should be good to go for a long time.

These things are very well made. I got a couple to make a ground plane antenna with some copper brazing rods. These are great in that instead of soldering the vertical to a pin on a normal 239 flange mount, you can solder the vertical into the cup. Works like a champ. If youre gonna make a ground plane antenna, get a couple of these!

They seem to be the quality I expected in the price range. There are better made connectors to be sure, but for the purpose that I bought them for (an offroad trailer) they fit the bill. No noticeable signal loss.

Works great

Working so far, I have mounted these to a copper plate so I can run 6 coax cables out a wall and ground all of the cables at one time.

Nice deep centers take a full sized PL-259 with no issue. Well machined and all around, good product. Id buy again

Center conductor was very flimsy. Bent out of shape with first use and then would not make contact. Bought ten of them, first two I used did the same thing. Been using this type of connector for 40 years and never had this problem.
