Hi All,


A friend hands me a roll of new cable and asks me if I want it, "of course" I say. I thought it might be RG-11 or something like it, but the ends are not "F" type. They are more like a BNC twist on type.

I want to know if I can use this as OTA antenna cable since I think it is about 100 feet and should be low loss.
Can it be adapted to coax or F type connectors be used on it?

According to the giver of said cable it is used in the cable TV industry in situation where low loss is imperative, but I think he may just be guessing.

Take a look:

The losses are double that of RG6 in the UHF band and, it's a 50 ohm cable used for medium power transmitting applications. It is not going to be useful in a 75 ohm application such as OTA TV reception. (Sorry)

BNC are mainly used for video equipment in studios, oscilloscopes, frequency counters, etc.
I never knew what effect using 50 ohm cable instead of 75 ohm would have, but using an adaptor at each end, may nullify the low loss benefits of the cable.

I thought so, it just seems too big and bulky. Too bad, at least it was free.

What can it be used for?

It would make good transmission line between a HAM radio or CB radio and the appropriate antenna... Though you would no doubt need to change the connectors or at least use adapters.

As Stereocraig mentioned, it may be useful in test setups with oscilloscopes, spectrum analyzers or signal generators.
