This is not a personal attack, but an attempt to politely discuss and hopefully resolve a technical disagreement. As already stated, I believe grounding the the coax shield and mast provides little if any suppression of interference. Therefor, someone who is not having problems with interference may read such a statement and then incorrectly conclude there is no reason to properly and effectively ground their antenna installation. So to the issue of 'benefit to the OP', given the OP's specific interest in this issue, if one or both of us are wrong, the OP deserves accurate information. Secondarily, both of us can benefit from being challenged to test our knowledge.
On one hand, you correctly caution me against overstating the danger associated with ignorance of grounding. On the other hand, I believe I have a valid concern about understating the value of proper/effective grounding.
I have always held the position that grounding the the antenna system is best practice. In an indoor/attic installation, I believe that connecting the coax shield to the the tuner chassis achieves that purpose minimally. Use of a grounding block or the ground lug on a splitter, connected to the building ground is usually inexpensive in terms of parts and labor, and a far superior form of protection should some unlikely nail be driven through a Romex power cable and coax.
