Product Description
Comet CTC-50M - Flat Window / Door Feed-Thru Coaxial Cable
The CTC-50M jumper allows you to get your antenna coax into the radio room without drilling holes in the wall or leaving a window/door open. The center core of the flat wire coax is "copper-clad steel". It was chosen for its strength and resistance to metal fatigue. The film is made of ALPET (ALuminum/PET plastic, same material as milk jugs) to resist damage upon closing the door or window. 24k gold plated female connectors are supplied with screws to attach the connectors securely to the wall/window frame. Close the window and screen securely to keep out weather while keeping your home secure without damaging the coax.
[ ARS STAFF NOTE] We no longer sell this cable but customers say it very durable compared with inexpensive flat cables. It allows a window or sliding door to close completely. Lost on VHF (144 MHz) is about 0.5 dB. It is difficult to notice in normal operation. UHF has slightly more noticeable loss than HF, but is acceptable. HF users report normal SWR (around 1.1–1.2:1) and no noticeable degradation in normal use. Installation matters, if the flat section lies tightly against aluminum window or door frames, a few users have reported increased SWR or impedance changes. Repositioning or adding a little spacing often helps.

WHAT CUSTOMER SAY
[ ARS STAFF NOTE] We no longer sell this cable but customers say it very durable compared with inexpensive flat TV type cables. It allows a window or sliding door to close completely. Lost on VHF (144 MHz) is about 0.5 dB. It is difficult to notice in normal operation. UHF has slightly more noticeable loss than HF, but is acceptable. HF users report normal SWR (around 1.1–1.2:1) and no noticeable degradation in everyday operation. Like any window pass-through, installation matters. If the flat section lies tightly against aluminum window or door frames, a few users have reported increased SWR or impedance changes. Repositioning or adding a little spacing often helps.

Excellent temporary fix
Just moved into a new house and have not had the opportunity to route all the cables permanently like I want. This is a fix that will get me through until springtime with y VHF antenna and G5RV. Good product, shipped very quickly.

The Difference between QRV and QRT!
I rented a Brick house with sliding aluminum windows. Drilling holes was out of the question. The CTC-50 allowed me to set up a 2m/70cm J-pole on the roof peak for my IRLP node. I had no problem with the PL-259 connectors I used; this may have been corrected by the mfgr. The only con... a bit pricey but I've yet to see anything esle like it!
