Actrully, my cable is RG59 - bonded foil 7% braid - (F5967 BVV) -
supplied and installed by rogers for digital TV and internet.
When I had a distribution amplifier on my line I also had 50 volts DV
on the coax.
RG-58 is never used for cable TV. Maybe you are thinking about RG-59
which used to be common but isn't used anymore because it has higher
losses than the commonly used RG-6 or RG-11.
I don't believe 13 or 18 VDC (the voltages used to power the LNB
depending on what antenna polarity is called for by the receiver) is
capable of delivering a shock but it sure sounds like a great story.
I know nothing about ComCast other than that they are a TON slower
than RoadRunner, at least in CT. My DH was stuck in CT during a 6
month computer nerd contract, and for whatever reason, the complex he
rented an apt. in would NOT allow RR, just CC. Well, they showed up on
time, were very fast, but the connection was so HEINOUSLY SLOW, he
realized that it was FASTER to stay home here in NY and use the RR
connection instead of being just .5 miles from the site. He scrapped
the apt and is now home 25 days a month and just rents a hotel on the
few days necessary. Yes, if he is in an office in CT it's still 20%
faster than if he's home in NY, but being in the apt. in CT was about
30% slower than being at home in NY, for free!
So...maybe comcast sucks, maybe not, but their service, in my DH's
experience, is EPICALLY SLOW. Of course, YMMV.
Evidently service varies dramatically depending on your location.
I just ran the speedtest.net test against our Comcast service and got:
