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

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

Excellent for my HF radio.

Bought to run non amplified loads, works fantastic for HF/VHF. Given the cost of good connectors is about $20 for a pair, and some cable to put between them and a nice chassis for each end, its not hard to price out and justify the overall price. Pros: Easy to install Little modification to pre-existing structures, maybe some screw holes or use double sided tape for mounting. Pretty good construction Works great for window use, my installation closes nice and easy, still seals well with it installed. (modern double pane vinyl) Cons: Not super heavy duty, not designed for high watt/amp use. Other thoughts: Not going to work with storm windows that you want to close. They are a good stop gap to get you on the air until you get a amp and run actual feed lines from your ham shack.

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.

Works great

Works great. Theres a reason they charge so much for a simple cable - because they can!

this product is exactly what i needed to feed a radio cable through a window while maintaining a functional weather seal

Works fine. No need to butcher your house.

Works as advertised.

Works great! Using it for a scanner antenna and getting that antenna outside made a world of difference, I don’t see any notice loss with this product.
