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.

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.

these work better than those barrel connectors and nuts. nice clean install if you use the correct hardware.

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.
