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

Works great for my setup! Would buy again

Works great

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!

Made my wife happy because I dont have to cut holes in our new home to get back on the air with amateur radio.

I am a new ham and was trying to figure out a way to run coax without drilling a hole. Saw this. A little expensive guy well made and works! Very happy. So far it is holding up very well. Access thru upper balcony door.

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

When I ordered this, I could find no mention that these feed-through jumpers worked with newer horizontal sliding vinyl double-pane windows. Being very energy efficient, I was concerned our 3 year old windows would seal too tightly for this jumper to work. But I can now tell you, it worked for our windows and very well. I purchased two of these jumpers, one for HF and the other for 2M/440. The cables are one on top of the other and Ive seen no interference between the two signals. This jumper solved my problem of not wanting to drill through our stucco walls. Now I can run both radios (HF & Dual-Band) with the window tightly closed.

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

Works fine. No need to butcher your house.

Installation of the window feed-thru was easy. Care was taken to protect the wire even more using additional padding. Before I connected the radio and transmitted - I wanted to check the VSWR. I connected a MFJ-266 HF/VHF/UHF antenna analyzer to the jumper which was connected to the antenna coax cable. Everything checked out - no surprises. I will order again.
