Any other house should have a similar ground. That's that the NEC is for.
And we do have multiple large antennae on our house. As the mast is the tallest object around, it has 000AWG wire bolted to it, running down the side, and into it's own 8' ground rod.
Please, put up, or shut up. Post a link to someone else's DATA on your 3 knot nonsense, or let wive's tales be wive's tails (do wives have tails?).
First of all 1 lightning strike is not 1 strike its 4 to 5 strikes (learned that in a 3rd world school)
If the 1st surge melts the knot. It will keep the others from doing further damage.
Suppression of transient surges and overvoltages is done by the use of MOVs installed in Shunt with the AC powerlines. It reduces the impedance to the surge. The impedance between the powerline and the ground will drag it to the ground. SURGE PROTECTORS CREATE A LOW IMPEDANCE TO THE PROTECTED DEVICE. A antenna is a different story cause by its own it can be a ground. But what does help grounding it when a powerline gets hit? The trick is to reduce the impedance TO THE device. If your thinking about creating a path quickly to THE ground you need something to be quick enough to clamp the circuit within 1 billion of a second. The knots help decrease the impedance. Plus computers and such are far away from the entry point normally so it assist bringing the impedance down.
And again its for extra surge protection. Its a free way to add more protection. Its not a replacement for a protector!!!!!
Op for brown outs, power outs and dips -> UPS
TO protect a UPS choose a surge protector
For upset other damage by surges, choose a surge protector
For I/O port damage, choose a data line protector
For extra protection you can try the........
