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

Still feel its too a little expensive for what it is, but it works well.

The right option when your in an apartment I have two of them one for vhf and one for hf Radio work

for 50 bucks you get a window passthrough with minimal power loss and you do not have to drill holes in your walls. Update after one year the cable is separating. It still works though

$60 for this?? I graduated to big power, and even my transceivers running barefoot will not work well with this. I ran a Heathkit HW101, Yeasu FT857D, FT1200DX, FT897, all had more loss using this than using a piece of square tube closed into a window with SO259/239 connectors, and N connectors, as well as ladder line, hard line and window line balanced cables. If you are renting, this is a very viable option, but $60!?!

If you cant go to the next level of having coax through walls to elevate your antenna, then this is the trick. Been using it about a month and really vastly improved transmit and receive on my Baofeng hand-held. Using now on my Kenwood TM-D710G and find it does well.

A lot more heavy duty and durable than expected! Very happy with my purchase! If they were a bit less expensive, I wouldve purchased another one by now.

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.

We have double hung wood windows. I did not want a panel in the window frame nor do I want to drill holes through our incredibly expensive siding. I know this is a tradeoff but one I have to make. I got two of these as I hope to try out at least two different antennas. I like that they are long enough to also fit under the outside window screen.

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

I am a new ham and was trying to figure out a way to run coax without drilling a hole. Saw this. A little expensive guy well made and works! Very happy. So far it is holding up very well. Access thru upper balcony door.
