Hi, Is it worth trying to use outdoor CAT5 to feed reversible Beverage? There are 4 twisted pairs inside, paralleling 2 for both directions will give something close to 50 or 75 ohms. Any idea what i
As a feedline, as in any "twisted pair" like old phone line was called, CAT-5 has been successfully used as a feed line for RF. There is no reason it should not perform any worse than 200-300 ohm rib
There is a test used when installing this cable commercially called "PowerSum NEXT". If you look that up you should be able to get an idea of the coupling between pairs. If I remember correctly it's
These are most likely to be single-number values that average the crosstalk over a broad frequency range, but the actual performance will vary as a function of frequency, and with the quality of the
FWIW, I have several runs of outdoor-rated CAT-5 cable to and from my tower. It is flooded and has a tough jacket to help stave off the chipmunks. 73, Pete N4ZR The World Contest Station Database, up
Ive run indoor CAT-5 about 250' to a remote building where a PC is located. It is elevated about 8', hung from the CATV hardline and control cable bundle, and has been in use about 12 years, about 10
the primary consideration is probably what Herb noted about I fully agree. I have a 300'+ outdoor run of CAT6 on my LAN. The portion which is not in conduit is seriously deteriorating from the sun's
You are likely correct. I have not reviewed the spec in some time, but it most likely is an average value over the LAN-used spectral range (likely in the high-kHz region up to maybe 100MHz or so). It
