I was working in Phoenix and was set up for a night cut, I was in position at 11:30 and opened the node up to get a look see as things were powered and if it matched the map. Not affecting the system mind you - just looking. Not two minutes later, I get a call from cox on my cell asking if I was starting my work early

You can make some good $$ if like was said, they can keep you busy. I think the worst part is splicing in the DC to the system - many times this must be done at night. If they have to have it on a certain exact leg - that is the worst. Some places will allow you to splice it on any leg it will fit easily on. Every place will say "most are allready spliced in you should only have a few to do" - by now, you should know that most are not, and this can really affect your production.
You must also run coax from the DC or tap to the power supply. Most times it is RG6 but some places want a hardline ran.
Hope this helps in your decision - Good luck! hope you make some big bucks!
