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

I bought one of those non-descript cell phone signal boosters to help me with the reception in my basement office. This jumper, while a bit pricey (I only paid around $70 for my booster), does the job just fine. I tested the booster with and without the passthrough jumper, and it has no detectable effect on the signal. I had to get a set of UHF/PL-259 Male to N Female Connectors to hook it up, and everything works well. I am in the early stages of planning my ham radio shack, so Ill be buying more of these. My wife takes a dim view of drilling holes in the 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!

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.

The other guys is longer haha

I run many rigs and because I use low power on all of them this co axial cable pass through is a go to for me. The pass through eliminates the need to drill holes through my home walls for cable.

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.

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.

Modern windows are tight with no room in the slides. This would not allow my window to close with this either in the side or at the bottom. Great idea, but it didnt work for me.

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

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