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

Great for feeding antenna around a glass sliding door and still close the door ok. Had one for few years and slamming the door on it so this was a replacement.

It’s expensive for what it is but it is the best thing I have found for feeding coax through a window. I added suction cups to it, 2 on each connection and it holds tight to the window and doesn’t beat the glass up in the wind.

They work and for a window sill in a house you will probably never have a problem, but if you use them for a rear window in a two seat pickup, Chevy Silverado, etc, you should modify it. The problem with a vehicle is the part that hangs outside and is exposed to the wind will eventually start coming apart at the flat cable connection. I luckily caught mine before it completely broke in two. It still has continuity through both conductors. To repair it, I laid the flat cable back along side the box that houses the connector and taped if tight against the housing on both ends. I will now wait and see how long it lasts as they are a little expensive. I will probably buy a replacement just in case it breaks during a hunting trip when I need it the most.

Great Solution to a Common problem, but it seems too high priced for what it is. I guess when youre the only one that makes these thats what happens. I would Suggest selling for $35......maybe more would be sold. Overall, Im happy with the quality and functionality of the product.

It work just like it was made to

Love it. Makes it work for HOA!

Save me from having to drill a hole in the side of the house for an LMR run.

These guys are PERFECT for those windows that open in non standard ways. I detected no signal loss with my MFJ Antenna analyzer and purchased a pair of them to bring in signals from my dual band VHF/UHF Diamond X200 and my MFJ vertical 8 band antenna. These guys are well made and durable as every Comet product I have ever purchased. These would work well for people who have to run an antenna through a condo door or even a RV window. Mine are secured into the window sill and cant move. Another plus is you can easily disconnect your antenna from the outside during lightning storms.

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.

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