Mostly accurate but as a practical matter total BS ............. Good grief !
The odds, yea I know, of having to fight with an insurance company because the ungrounded dish caused a loss of my property are less than hitting the lottery 3 times running.
If you install a dish at your own house with an improper ground, chances are small that it will cause your house to burn down. If you install a light fixture at your house improperly, chances are higher, but still small that it will cause your house to burn down. I have heard of several cases where homeowners installed larger items such as dryer outlets or AC units that did cause fires that burned their house down.
For professional construction trades such as electricians, there is usually a fairly rigorous training procedure. For IBEW electricians, you start with a four year apprenticeship which includes working and taking classes. You then can qualify to be a journeyman electrician. After four years as a journeyman electrician, you can qualify to be a master electrician. During all of that training, you learn the NEC code. You learn how to size wires. You learn how many wires you can put into a conduit. You learn the proper ways and methods to install a ground. If you consistently install systems that do not meet code, you will not be in business as an electrician very long. If a significant portion of engineers and electricians do not feel that the code is proper, there is a mechanism for making suggested changes back to the National Fire Protection Association(NFPA), the group who publishes the NEC.
The satellite dish installation industry would not need as rigorous a system as the IBEW to train installers. But it appears that with many installers, the training consists of a few weeks consisting only of methods of mounting and aiming a dish. Imagine a situation where an installation company consistently does not ground the dish properly or at all.(Not uncommon) If the house burns down, a lawyer could sue the installation company. They could show that the company consistently violates the building codes. They could argue that violating codes puts people at risk. They could argue that this customers house was at risk because of the installation companies disregard for building codes, and it burned down. If the lawyer makes good arguments in court, the installer could potentially have to prove that the fire was caused by something other than the satellite dish to keep the jury from deciding based upon pity for the customer and contempt for a company that thumbs their nose at building codes.
I would say that installation companies should consult with code experts to develop guidelines for their employees. They should train their employees on how to properly ground dishes. If enough of the installation companies have experts who believe that the current code is overreaching, they should appeal to the NFPA. What is not acceptable is having employees installing systems who have no idea what the requirements are.
