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

Works as advertised.

This was exactly what I wanted. So far it lives up to its description. It seems sturdy. It was overpriced for what it is, but when youre the only game in town you have that latitude. I wish they made something similar for running my ground line.

Great for feeding antenna around a glass sliding door and still close the door ok. Had one for few years and slamming the door on it so this was a replacement.

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

Windows in our leased house are the swing-out variety, so the usual slide-window pass-throughs dont fit. I eventually bought three of these, one for HF, one for VHF and one for UHF. Insertion loss is better than I expected, and SWR is acceptable in all three bands. The only downside is that being as thin as they are theyre not the sturdiest. Best used in locations where you can put them in and then dont open/close the windows a lot.

I bought one of those non-descript cell phone signal boosters to help me with the reception in my basement office. This jumper, while a bit pricey (I only paid around $70 for my booster), does the job just fine. I tested the booster with and without the passthrough jumper, and it has no detectable effect on the signal. I had to get a set of UHF/PL-259 Male to N Female Connectors to hook it up, and everything works well. I am in the early stages of planning my ham radio shack, so Ill be buying more of these. My wife takes a dim view of drilling holes in the wall.

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 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.

Good product

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.
