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

Able to close window on cable and not lose heat. Very low loss of power. Small db loss when inserted.

Had to replace after 6 months

Great product if you dont want to drill holes in your wall.+

Works great for my setup! Would buy again

Works fine

Absolutely garbage. Doesnt work at all, and its extremely flimsy.

To avoid drilling the new double-glazed windows or the 60 cm wall (the house is over 100 years old) to pass the antenna cable, I tried this product. The flexible part adapted very well to the path between the two parts of the window, bending in places. The window opens as usual, you do not notice the presence of the passer-by. The antenna receives as usual, I have not noticed any degradation in performance, not even at the signal strength measuring unit. For now I dont comment on the durability because I bought it recently, but it looks sturdy. Its not cheap, but its well done.

It work just like it was made to

I was a bit leery at first, but after installing two of these, one at my house and one at anothers house, I looked at the feed on my analyzer, and I didnt see any detectable difference in loss or impedance bump with the feed-through, compared without it. People I tested with also noticed no difference.

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