Kinda hard to win an argument with him, no?
I'm not worried about winning/losing, just providing accurate information. There is so much good help provided on this forum, and peds has done a lot of it, but none of us has a stranglehold on perfection. We all make mistakes. It's much better if we just learn from them and move on, otherwise our credibility disappears.
I would also note that I have not had a problem with any of my APC units (all of which are non-sine wave) powering any of my devices, which include, but are not limited to:
HR20 series DVRs
HR21 series DVRs
H21 receiver only
HR24 series DVRs
HR44 series DVR
Samsung 60 LED/LCD
Assorted Video Recorders
Onkyo SR-605 HT Amp/Rx
Assorted BluRay Players
I don't seem to possess any electronics that can't handle the sine wave approximation that the assorted consumer grade UPSs put out...at least the ones I have, which are mostly APC. I have 3 of them in my 7 foot rack for the Media room, and another 4 in the basement for the computer/ham radio setup. There are 3 more throughout the house for other things I want to protect. If something could benefit from a surge protector, I give it a UPS, which has surge protection built in to it, and auto-switches away from the line, should it become "dirty" or non-existent.
I also have a fairly extensive single point ground system which all the stuff is connected to, including a few thousand feet of buried radial wire.
All that, done the right way, and there is still no certainty that a direct or near direct hit won't fry things. Been there, done that, $13,000 later, redid it all, as the hit came in the telephone line/network connection and fried every network connected device in the house, plus all phone stuff. Obviously, I had not sufficiently protected the phone/network lines. Nothing was damaged from the AC side of things, not one item. If it had a wired connection to my network, it was gone. Wireless stuff was fine.
Grounding for lightning mitigation is a very complex and demanding issue. Dish grounding discussions on these forums are more often than not, simplistic and error ridden. (when it comes to lightning mitigation which is an RF problem, not a DC/Safety ground issue). I digress....yet again...sorry.
