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

I havent had any problems using these 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.

Have not used yet but they look of good quality bought to make a window pass-through havent had time to do it yet

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.

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.

Can see . Cheeply made but functional. Dwight

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

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.

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
