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

Fairly expensive for what it is, but it works. As previous reviewers have noted, I dont think you would want to raise and lower a window on this device too frequently. I operate HF, and I dont see any negative SWR impact with this cable.

Next time. Im just going to buy SO239 to SO239 bulk head fittings and drill a hole thought a piece of wood.

These guys are PERFECT for those windows that open in non standard ways. I detected no signal loss with my MFJ Antenna analyzer and purchased a pair of them to bring in signals from my dual band VHF/UHF Diamond X200 and my MFJ vertical 8 band antenna. These guys are well made and durable as every Comet product I have ever purchased. These would work well for people who have to run an antenna through a condo door or even a RV window. Mine are secured into the window sill and cant move. Another plus is you can easily disconnect your antenna from the outside during lightning storms.

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.

Love it. Makes it work for HOA!

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 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.

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)

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.

If your running a rig in a condo, these are what you need, no holes, threw the window jam, work great.
