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

Meets all expectations

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.

Absolutely garbage. Doesnt work at all, and its extremely flimsy.

Not exactly what the doctor ordered but the next best thing. Haven’t installed it yet but anticipate that it will work.

To avoid drilling the new double-glazed windows or the 60 cm wall (the house is over 100 years old) to pass the antenna cable, I tried this product. The flexible part adapted very well to the path between the two parts of the window, bending in places. The window opens as usual, you do not notice the presence of the passer-by. The antenna receives as usual, I have not noticed any degradation in performance, not even at the signal strength measuring unit. For now I dont comment on the durability because I bought it recently, but it looks sturdy. Its not cheap, but its well done.

Works fine

This is a good solution for running a coax cable into the house with out making holes. I is a bit pricey for what it is.

This product solves the problem of getting a coax feed line into the house without drilling through the wall.I use it with my Icom receiver with a outside antenna. This has coax connectors on both ends and is thin enough to close the window no problem, it can also go under a door if you need too do that. I am just a DXer but hams can transmit with up to 100 watts with this thing. Very good solution to an old problem, for me a must have.

Expensive, but well made. No noticeable negative effect on SWR. Two more connections in the run, so has be some added signal loss, but I have no way to measure just how much. It certainly seems low enough that it does not matter to me; I didnt want to have to drill holes in the house walls, and this is a great solution.

The convenience-factor is high in this one. It gives you a chance to breath and decide exactly where you want to drill that hole in the wall, rather than jumping the gun and drilling in a location youll regret later. Best left in-place and only moved occasionally, but in general they wear well (just in case your final decision is slow coming).
