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

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.

I was surprised by how well built this pass through was. It works as advertised. Great design with zero signal loss. I definitely would recommend this product!

Modern windows are tight with no room in the slides. This would not allow my window to close with this either in the side or at the bottom. Great idea, but it didnt work for me.

Did not expect to have 1.01 SWR with a 25 foot LMR 400 cable on 2m and 70cm. This saves me anther hole in my wall during the winter, this is a temp setup until its nice enough to drill.

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.

Excellent for my HF radio.

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.

Very convenient. I hope they do they do another one with high power rating (Max Power: HF 100W PEP, VHF: 60W FM, UHF: 40W FM, 900MHz-1.3GHz: 10W FM)

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.

Works great
