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

I have three of these in use and I love them! Im using them on 40 through 10 meters and they have virtually no impact on SWR. Im using them as a temporary measure until the weather improves, but they have been working so well that I can see them being used in permanent installations.

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

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.

This though cable works great. Can actually close Windows on it.

The convenience-factor is high in this one. It gives you a chance to breath and decide exactly where you want to drill that hole in the wall, rather than jumping the gun and drilling in a location youll regret later. Best left in-place and only moved occasionally, but in general they wear well (just in case your final decision is slow coming).

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 product

Its hard to pay that much for this product but its well built and works as intended.

Works great. Better than drilling a hole through the wall. Ive had it about a year and it has been a very good product.

We have double hung wood windows. I did not want a panel in the window frame nor do I want to drill holes through our incredibly expensive siding. I know this is a tradeoff but one I have to make. I got two of these as I hope to try out at least two different antennas. I like that they are long enough to also fit under the outside window screen.
