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

If you cant go to the next level of having coax through walls to elevate your antenna, then this is the trick. Been using it about a month and really vastly improved transmit and receive on my Baofeng hand-held. Using now on my Kenwood TM-D710G and find it does well.

Using this on a window that seldom opens. I didnt measure any lose loss in signal strength. Accurate description and performance.

Easy Peasy

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 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.

Works as advertised. Doesn’t destroy the weatherstrip and the antenna works like a charm.

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).

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.

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

My second one. It works great. No problem making the connection to my other coax through a window and a storm window! Sturdy and great quality. Way better than the plastic window pass thrus I have that created horrible cold drafts in winter and a cheaper solution!
