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

Good product

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.

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.

I run many rigs and because I use low power on all of them this co axial cable pass through is a go to for me. The pass through eliminates the need to drill holes through my home walls for cable.

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.

I was surprised by how well built this pass through was. It works as advertised. Great design with zero signal loss. I definitely would recommend this product!

I got my ham license (WB8ERT) on April 30, 2021 and as a renter (apartment) contacted the landlord about putting up an antenna. I promised to restore any and all modification, but the answer was no. This connector allows me to keep outdoors (on my air conditioner) my antenna (Nagoya UT-72 Super Loading Coil 19-Inch Magnetic Mount (Heavy Duty) VHF/UHF (144/430Mhz) Antenna PL-259), which I also purchased here on Amazon.com. Please note I rated this antenna a 5 star in my Amazon.com review. My radio is an handheld unit (AnyTone AT-D878UVII Plus). The connection from the radio uses all Amazon.com purchased wiring. Radio -> Superbat RF Coax SMA Male to UHF Female SO-239 Cable + 2pcs SMA Adapter SMA UHF Female SO239 Adapter -> RG58 Coaxial Cable 49.2ft,UHF PL259 Male to Male Cable 50 Ohm Low Loss -> To this unit -TC-50M CTC50M CTC 50M CTC/50M Original Comet Window Feed-Thru Jumper -> Finally to the antenna (see above). Thus far for UHF, VHF, and DMR Ive not had any problems with any purchases from Amazon.com ham gear. I can highly recommend this connector to those whose landlords dont want any modification even with a promise to restore to original condition.

Great for feeding antenna around a glass sliding door and still close the door ok. Had one for few years and slamming the door on it so this was a replacement.

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.

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.
