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

This has turned out to be a great solution for getting a coax line out of the shack. Bought a second one and switch between 2 antennas. I have double sash windows, so in my case I can still open the window without disturbing the Comets CTC-50Ms.

it kind of pricy but now I dont have to listen to my wife complain about the window and screen open to run my coax into the house...I have dual pane sliding vinyl windows and i can close them and lock them with out disconnecting my coax...I have not heard anyone say my signal has dropped since I installed it but I only use it for 2 meter/ 70 CM and max 50 watts if you want to close your window and dont want to continue to use your radio just get it

Easy Peasy

Not too much to say here. It works as advertised and keeps me from having to drill a hole in my wall.

Did not expect to have 1.01 SWR with a 25 foot LMR 400 cable on 2m and 70cm. This saves me anther hole in my wall during the winter, this is a temp setup until its nice enough to drill.

$60 for this?? I graduated to big power, and even my transceivers running barefoot will not work well with this. I ran a Heathkit HW101, Yeasu FT857D, FT1200DX, FT897, all had more loss using this than using a piece of square tube closed into a window with SO259/239 connectors, and N connectors, as well as ladder line, hard line and window line balanced cables. If you are renting, this is a very viable option, but $60!?!

Does what it says it will and saves me drilling holes in wall

Works fine. No need to butcher your house.

Had to replace after 6 months

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.
