Here's one article
that describes the "hundreds of thousands" of joules in lightning, so the "pathetic" surge protectors or "power conditioners" are not doing any good for very-high-surge events like lightning, only for mild surges. (You can find many more articles like this.)
The article also mentions "earth" many times to reinforce the fact that you need to go to mother earth for grounding. If you don't find a metal rod driven into the ground near your foundation with a wire attached, you're not "grounded." You don't want your "ground" to be some other part of your home's wiring or structure.
Your pictures show that you don't have a surge protector at the top entry point for your power lines, which would normally be attached by the power company right at the downward portion of the entry pipe, way up top, as shonw in pic below.
I don't think you can divert a lightning strike from your power-line entry point with an earth ground and even some sort of wiring around the metal pole to ground would probably not divert a strike from the power lines themselves... dunno anything about that. The only other way I know of to protect your power lines besides that add-on surge suppressor is a modern, surge-suppressed main electrical box which, of course, no one would consider unless doing a complete remodeling like we did 10 years ago... I think they "disconnect" under extreme input voltage but I'm not sure they're fast enough... maybe so, but I don;t want to find out..
That in-line coax "protector" in the box looks like one of those with some minimal internal surge protection, and there's no wire on the screw that goes to ground via a heavy duty wire (less than 10 ft) to a spike driven into the "earth.
I think if you read enough articles on lightning strike you'll understand that buying "surge protectors" will do little to protect your equipment from strong over-voltages. They only help to dissipate mild surges, and they're certainly not "grounded" to dissipate bigger surges they're not designed for.
As the linked article states, the only way to protect against a direct
lightning strike is to buy more insurance and/or install actual lightning rods (that will divert a strike to them and to the earth ground to which they're attached).
