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

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

Seemed a little high but decided to give it a try. Worked well in my application. Window is closed and locked. May get another.

I bought one of those non-descript cell phone signal boosters to help me with the reception in my basement office. This jumper, while a bit pricey (I only paid around $70 for my booster), does the job just fine. I tested the booster with and without the passthrough jumper, and it has no detectable effect on the signal. I had to get a set of UHF/PL-259 Male to N Female Connectors to hook it up, and everything works well. I am in the early stages of planning my ham radio shack, so Ill be buying more of these. My wife takes a dim view of drilling holes in the 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.

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.

This though cable works great. Can actually close Windows on it.

Good product

Made in Japan...nuf said.

I like the profile of these window jumper cables because I don’t like the larger pass-through units. I have one for each of my antennas and built a small cover for them to help protect them from the rain and snow we get where I live. They are compact, but very well built and I haven’t noticed any change in reception or transmission quality. I’d buy another if I needed to without hesitation.

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.
