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

    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.

    This is used on a manpack setup for a 2m radio. 3/4in hole for the pass through. 1in screws work with 3/16 aluminum. Nice connectors

    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.

    These are going to be part of the back panel of my SKB Go-Box. A jumper from the radio to a panel were I can easily mate the antenna coax to this bulkhead.

    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!
