Comet CTC-50M CTC50M CTC 50M CTC/50M Original Window Feed-Thru Jumper W/UHF Female (SO-239) Connectors at Each End

I love the idea of this type of jumper. It is thin so you can smash it in the window and it will still work. The idea being that you dont need to drill holes in your house to run an antenna cable in. I use this for connecting a HAM radio in to my basement office. Im not a big fan of drilling holes in my house to get cables installed and connected, which is why I installed conduit in the walls of my house for everything that I could consider at the time the house was built. I obviously didnt consider getting in to HAM radio, so I didnt put any conduit to that side of the house. This jumper allowed me to get an antenna cable in to the house without needing to drill a hole. It has been installed in the window now for a couple of months, during fairly cold weather. I have not noticed and leakage from the window where it is installed. One thing that I have not yet tried is to put the screen back in place. I am not sure if the screen will have enough force to push the cable out of the way, or if it will just bend the screen. But, I will probably find out when it gets a little warmer. Overall, I am happy with this jumper, but I deducted one star because these jumpers seems insanely expensive for what they are.

Had to replace after 6 months

This is a good solution for running a coax cable into the house with out making holes. I is a bit pricey for what it is.

Great product if you dont want to drill holes in your wall.+

Next time. Im just going to buy SO239 to SO239 bulk head fittings and drill a hole thought a piece of wood.

Great design idea and worked great for me.

Fairly expensive for what it is, but it works. As previous reviewers have noted, I dont think you would want to raise and lower a window on this device too frequently. I operate HF, and I dont see any negative SWR impact with this cable.

Works great for my setup! Would buy again

Works great! Minimal signal loss if any depending on frequency you are using to transmit on.

They work and for a window sill in a house you will probably never have a problem, but if you use them for a rear window in a two seat pickup, Chevy Silverado, etc, you should modify it. The problem with a vehicle is the part that hangs outside and is exposed to the wind will eventually start coming apart at the flat cable connection. I luckily caught mine before it completely broke in two. It still has continuity through both conductors. To repair it, I laid the flat cable back along side the box that houses the connector and taped if tight against the housing on both ends. I will now wait and see how long it lasts as they are a little expensive. I will probably buy a replacement just in case it breaks during a hunting trip when I need it the most.
