these will be good for the ability to plug in a socket socket in the wall of your camper and be able to bring the antenna connection into the camping trailer without an open hole in the wall.

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

Pulled the protective caps off, completely fell apart... no way it would hold the connection or be able to be waterproof...

Works well, was easy to install. Just be aware that they have no mounting screws so you have to purchase those separate...which in the long run is better depending on what you are mounting for.

What can be said about there simple but build is excellent cables thread on smoothly and long enough. I used two sets to build a wall pass through on a grounded copper plate worked out perfectly.

I use these couplers to DIY build my own window multi coax feed-through panels. After installation, the panel is then grounded directly to nearby ground rod. In this particular case, the cost of parts and labor, provide for a better and stronger panel than the leading commercial manufacturers.

Works as expected. Mounted in a 1U blank using a step bit (5/8 final size).

I havent had any problems using these connectors.

This is great for a pass-through that needs to be connectorized on both sides of the wall or bulkhead. It is also useful as a base connection for making your own UHF or VHF whip antennas.

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!
