Flat Cables
These frequently give problems with Dish Pro in my experience and neither I nor most of the guys I work with will use them for this reason and also for mere economic practicality, WE have to pay extra for those as no Dish install house I'm aware of supplies them to their guys. Why are WE supposed to EAT THE COST of every oddball supply that ISN'T used in 99% of work? Dish Network pretty much FORBIDS passing the cost along to the customer. DirecTV doesn't but a lot of DirecTV contractors who sub work to you do.
Mis-Pointing
A compass/inclinometer like that offered by Suunto is required for this work, and every address can be looked up online for its exact pointing angles, never mind just simply inputting the zip code to the receiver set-up screen. Getting this completely wrong is insane and the mark of someone who wasn't trained at all or by a trainer who was incompetent.
Grounding
NEC regs are where local codes START and this requires that the dish assembly be grounded AS WELL AS the shield layer of the coax at the ground blocks. Ground MUST be to the household ground, NOT a separate ground rod, NOT to concrete, and NOT to hot water, oil pipes, or for crying out loud, gas pipes. This means to cold water where it enters the foundation before the water meter IF the cold water is strapped to the service ground, an eight foot ground rod IF the ground rod is strapped to the service ground, or to the electrical service panel conduit. Anywhere else is asking for problems.
Bad Installers
It's been my experience that 75% of installers are under twenty-five, not trained or badly trained, and motivated solely by making big bucks which they only can if they A)install through trees during the fall and winter, B)fail to take time for elementary grounding and tying down, and C)cut every corner possible.
What you have to remember about them is that they're largely eating the cost themselves of all supplies which can run over $200 per week, they are faced with as bad as 70% No Line of Sight, and 50% of all MDU installs failing to have permission to drill and install or with explicit condo/apartment rules which are so restrictive as to make it impossible such as requiring the dish to be no higher than three feet off the ground and five feet from the common wall to the domicile and in back of the building when line of sight is from the front only.
Never mind gas costs running as much as $600 per week.
DNSC guys are largely paid UNDER $12 per hour which is more than $3 per hour LESS than your average warm body tossed into an IT trench roll-out job with a tech temp company. They typically don't have the option that in-house cable guys have of calling dispatch and having jobs that they're running late on getting to pulled off their schedule and sent to someone else and are expected to get a job done no matter how complex, if it has line of sight.
Contractors are often in a worse position as they are almost totally treated as employees for the purposes of command and control and as contractors solely for the purposes of avoiding tax withholding and benefits which in every state in the USA is a flagrant violation of labor laws and given the failure to withhold, is TAX EVASION. We either put up with it or go hungry without work fighting a fight we will win but without any pay in the meantime.
On top of this, we have to deal with customers who vary between being totally normal and nice to totally nuts and sometimes downright dangerous, always given absurd expectations by a sales force which LIES THROUGH THEIR TEETH whenever they get the chance. "No problem. Our guy will put it on a pole at the back end of your farm and trench the line back to your house no matter how far it is."
Yeah, I'm gonna put in a twelve foot pole and trench seven hundred feet of .5 in. hardline, at my cost, just to get paid $70. Or mount the dish on a mast mount FORTY FEET HIGH.
