Nice. It would appear that you are not the prick most people in other hemispheres would have us believe.

Many many moons ago when cable TV was still analog, I put an A/B switch on the main line of my cable and used the B side to feed my distribution amp in which the output was connected to a set of rabbit ears and the A side to feed the cable box. That setup broadcast the whole VHF spectrum to any TV in the shop I would put a clip lead to. One day the cable guy comes in - they had been driving around "sniffing" for leakage, and my store was a real hotspot. He thought I had an open ground, but I told him I knew where the bad crimp was and threw the switch to A and the problem went away. The next day I went back to using the B side and a couple of months later they came in again, so they must have sniffed routinely , so I abandoned the plan. I should have tried broadcasting the output of the box alone - maybe they wouldn't have bothered me if it was a narrow spectrum.



That stunt could have wiped out communications for emergency
vehicles on the VHF high band, the two meter ham band and airports. You
could have indirectly caused people to die. We had people do that in
Apartment buildings, near Cincinnati. We had to install monitors in all
of our trucks to find them as soon as possible. If the FCC got involved,
it could have lead to time in prison. Cable TV uses those frequencies on
a shared basis, under the condition that leakage levels be maintained.
On big problem was morons slipping 300 ohm flat antenna cable under a
carpet, to move the TV to another location. It could be detected from
blocks away. Our sniffer system was outdated, but the video carrier for
MTV was on the right frequency so we could still use the receivers.
