I figured I would try and get as prepared as possible for the up coming spring T-storms. Yesterday I purchased 3 OPEK LP-350A lightning surge protectors. They are rated to 350w DC discharge at 50 ohm with less than 0.1 db insertion loss. I have a 2m/70cm Diamond X50, a Homebrew dipole, and a Solarcon A99 10 meter vertical hooked up using LMR-400 coax to a box containing the surge protectors then routed inside my Shack(basement) to my rigs. I have the Lightning surge protectors mounted to a copper bar then grounded to a 9 ft copper rod in the ground with 8 ft of #8awg green insulated wire. I also have 9 foot of the same wire running from the grounding rod to a grounding bar inside my shack. Am I on the right track with what I have done so far? I am very much open to constructive critiques and suggestions from the smarter people than me Thanks, in advance! |

The issue for most hams is properly bonding the electrical service entrance to the shack ground--for many hams--the most likely target for lightning is the overhead electrical wiring. And, if the most likely destination is the shack ground, because you did such a great job--you need to provide a good outside the house path between the two. Tom Rauch W8JI has excellent pages on station grounding. http://www.w8ji.com/station_ground.htm We have web a page on lightning protection http://www.arrl.org/lightning-protection Zack Lau W1VT ARRL Senior Lab Engineer |
