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

Meets all expectations

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.

Ive had my Comet Window Feed-Thru Jumper in my closed window for at least a year; maybe longer. It still works like new. Its a simple, but very useful product.

Great design idea and worked great for me.

Seemed a little high but decided to give it a try. Worked well in my application. Window is closed and locked. May get another.

I like the profile of these window jumper cables because I don’t like the larger pass-through units. I have one for each of my antennas and built a small cover for them to help protect them from the rain and snow we get where I live. They are compact, but very well built and I haven’t noticed any change in reception or transmission quality. I’d buy another if I needed to without hesitation.

I really like the idea of this product. It will allow me to bring a 2mm 70cm in without drilling holes in the wall and I don’t have to worry about leaving a window open. I haven’t installed yet but will be using this to connect to the Comet GP-3 and will soon have it operational. Would like to have one to use for the HF Bands.

Works as advertised.

Works great

Love it. Makes it work for HOA!
