ALL of the above.
If your neighbor is illegally "jacking"' into your cable signal, they might
simply strip the cable and wrap a wire around the exposed wire...very leaky.
More importantly, cable systems must not leak and interfere with comms
to/from overflying aircraft (et.al.), including VOR navigation beacons,
nor any other communications band user. Degraded in-home connectors,
damaged outdoor cables, as well as illegal tampering can result in a problem.
Cable uses nearly ALL frequencies, from CH2 through 860 MHz (some 1 GHz)
for video/data, and BELOW CH2 for reverse link from cable boxes and modems.
Hence, that includes the FM band, military bands and many Ham radio bands.
