All the grounding info I have seen mentions no sharp bends, or any bends
if you can help it when bonding tower legs, etc to ground rods or ground
rings as it raises the impedance to the ground connection. I can see a
loop in the coax being beneficial as a supplement to a ground system,
but definitely not as the only precaution. It takes a well designed
lightning ground system to take a direct hit without any damage and I
have never seen one in a residential setting. I know several mountain
top repeater sites that take hits all the time with no apparent damage
but the entire site including the building, tower and electrical system
were designed from the start with lightning in mind.

Hello:

Anyone have any thoughts on (hopefully not experiences) whether putting a
loop of, e.g. 1 foot in diameter,
on a coax run from an outdoor receive-only antenna has any merit as far as
helping any emf lightning induced pulses from traveling into a house ?

Have heard about this, but it's hard to believe it would actually do
anything in practice.
But,... ?
