[RFI] Comparing Lightning Arrestors?

[doc at kd4e.com]

I could put the blocking arrestor after the HD-1480 switch and ground
it to the connex (steel shipping container) and then a non-blocking
one at the entrance to the house - grounded to the whole-house common
ground.

That would peel-off much of the lightning surge and help to defend
the receiver(s) better than only the non-blocking arrestor at the
house, would it not?

I understand that in the added device there is some small loss and
an added step of potential hardware failure (not only the device
but the extra coax jumper).

> not need the block to achieve the same level of protection. --Mike, WV2ZOW
