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

Works great! Window closes completely. I use one for 2 meters and another for HF.

Seemed a little high but decided to give it a try. Worked well in my application. Window is closed and locked. May get another.

This is a good solution for running a coax cable into the house with out making holes. I is a bit pricey for what it is.

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.

...I bought one!!! Then....I bought two more! If you cant build your own cables or dont want to drill a 1 hole in your house to pull 1/4 or 5/8 cable because of the connector and let mouses in???? No matter what you may think...?.... this product is the answer. I put myn over the top window of double hung window. Semper Fi! Godspeed!! KC3GDY

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

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

This is intended as a 50 ohm flat window sash pass-through for coaxial cable used by amateur radio operators or others who need to get the coax from outside to inside without drilling a hole in wall or window sash for coax. It is quite flat with overall thickness of about 1/16 inch so it can use the space between the window sash and frame. It is well constructed with sealed joints on the ribbon conductor.

I have three of these in use and I love them! Im using them on 40 through 10 meters and they have virtually no impact on SWR. Im using them as a temporary measure until the weather improves, but they have been working so well that I can see them being used in permanent installations.

It does what it is supposed to do, but the price is a bit high. I use this to provide a connection between my patio and my back yard via the patio door. So far, i am only using QRP power levels. Since I install and remove it when I am done, my only concern is how well it will hold up over the long term. So far, it appears to be well built and thus, so far, worth the price.
