i don't think that that many "people" have been electrocuted. there are 2 things to be concerned with:
1. migration of static electric across other electronic components....it happens. seems like i see it more on some equipment platforms than on others. notably, dish network dual tuner receiver models and mainly the 522,625,322. again i see it (meigration) on the satellite internet platforms. both hughes and wild blue. if you've been doing this kind of work long enough you'll have noticed from time to time a slight tingle when holding the outside of the connector. thats static electricity. i would suspect though that it (grounding) would be a biger concern on catv. the service drop can pick up a static electric charge from the main line (aerial). generally caused by induction or a migration from other utilitys (electric). not to mention that aerial line is more likly to see surge damage (lightening) than an 18'' dish. static is real. and it can shorten the life of if not damage electronic components.
2. liability. true story: tech goes to a house. installs dish net. several months later theres a thunder storm. theres a lightening strike. house burns down. local fire marshall blammed it on the satellite dish not being grounded. luckly the tech had a general liability policy. would that lil 12ga wire have saved the day? prob not. but at least his ass would have been covered.
what may have got the failed qc may have been the installation of the ground block it's self. drip loops, proper attachment. properly installed, it's not such an eye sore. it's when there are wires hanging, sagging, no attachment, no drip loop that make qc techs wet their pants.
in short. attach it, loop it, ground it. if asthetics is a real concern...install a primise box ($2-$5) and upsell it to the customer installed for $20.
