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

Not too much to say here. It works as advertised and keeps me from having to drill a hole in my wall.

Well I have 2 of these but now wish Id just went with a regular window feed panel, would have been cheaper and would have worked better. This worked great until recently where I notice my swr shooting up high on vhf/uhf. Bypassed this window feed line and went straight to the radio and the issue disappeared. Weve had several strong thunder storms over the last couple of weeks so Im guessing some moisture must have gotten into the connector on the outside side. Maybe I should have wrapped it in plastic wrap or something but I guess I figured it was built to be outside so never really thought it needed it. If they didnt cost $55 each I would have just considered it my own fault for now weatherproofing it but at this price these things should be bullet proof out of the box.

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.

Does what it says it will and saves me drilling holes in wall

Meets all expectations

Easy Peasy

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.

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.

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.
