    "I was first licensed in 1980 and am a 20 wpm EXTRA. "

    Am I suppose to be really impressed? Who cares if you are a codie or no codie. Being a codie makes you no better than those none codies. Gee Wiz man. A hams a ham. Knowing code does not make you Albert Einstein. You can know code and still be as dumb as a box of rocks!!

    He didn't post it, someone else decided to make a big deal about the guy's comment by trying to belittle him using his qrz page. Pathetic.

    FBI:

    Not a hoax nor April Fool's gag!

    The purpose of a leaky line antenna system is for the entire length of the cable to serve as the antenna for the purpose of "filling in" dead areas, etc., that cannot easily be covered by a regular antenna. With many such systems, the far end of the cable doesn't really have to be terminated although I usually installed a 47-ohm or 51-ohm resistor across the far end of the cable. The less the power delivered to the far end of the cable the better since the basic idea is to have the signal, both transmitted and received, distributed along the entire cable instead of being concentrated only at the far end.

    Depending on exactly where the system is installed, the distance, to the antenna, usually doesn't have to be more than a few hundred feet and often less than a hundred feet. In tunnels, the distance may be measured in tens of feet. The whole idea is that radio communications are possible within areas that would, otherwise, be completely "dead".

    Leaky line antenna systems are used for specific applications and are not used for general applications.

    Here are a couple of Internet sites with information on such installations:

    https://www.itu.int/dms_pubrec/itu-r/rec/m/R-REC-M.1075-0-199409-I!!PDF-E.pdf

    Leaky line antennas are being used a lot these days to provide WiFi access within buildings and other areas that are shielded from "normal" antennas. However, they have been used, for decades, in the two-way radio arena.

    We use leaky line at our building to improve WiFi coverage throughout. It's cheaper than repeaters or multiple antennas, and does the job fine.

    Rat Shack coax may well have qualified for that, but I have no idea what we're actually using, that's up to the I.T. guys who do the crawling around.

    You can't say that "RG-xx" from a given source is always crap or good. RS had some good stuff and Belden et al makes some cheesy stuff. Ya gotta compare part numbers. A look at Belden's catalog (link) shows a widely-varying quality of a given RG-number. About the only RG-cables that are consistent are those that carry a Mil specification (such as RG-213/U, RG-58C/U). And even then, those two aren't the best available in their respective sizes... they're just guaranteed to meet a specification.

    follow both links. No one posted that they were 20wpm, it was taken from his webpage to ridicule the guy's comment
