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

Works great! Minimal signal loss if any depending on frequency you are using to transmit on.

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.

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

My second one. It works great. No problem making the connection to my other coax through a window and a storm window! Sturdy and great quality. Way better than the plastic window pass thrus I have that created horrible cold drafts in winter and a cheaper solution!

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.

Great design idea and worked great for me.

Works as intended with little or no increase to SWR. I added some all-weather electrical tape to both sides of the flat strap to give it increased protection from the tight fit.

Installation of the window feed-thru was easy. Care was taken to protect the wire even more using additional padding. Before I connected the radio and transmitted - I wanted to check the VSWR. I connected a MFJ-266 HF/VHF/UHF antenna analyzer to the jumper which was connected to the antenna coax cable. Everything checked out - no surprises. I will order again.

Able to close window on cable and not lose heat. Very low loss of power. Small db loss when inserted.

Excellent for my HF radio.
