Added a 4th lightning arrestor to the ground panel

When I installed the 30m I used the coax run into the house from my 2m antenna. I finally bought some more coax(Davis Bury-Flex, I find it easy to work with than LMR-400 and it’s about the same as far as losses) so I installed the last lightning arrestor I have room for. There’s been a crazy bird squawking in the yard all day and he kept divebombing me the whole time I was install the connector. Bird

Grounding and Bonding

Being in Florida I’m concerned about lightning. Someone at the club recommended the ARRL Grounding and Bonding book which I purchased and read. I followed the information in the book to create a single point ground panel outside the house using a DX Engineering utility box . Coax from the antenna comes into this box and into a lightning arrestor, then into the house where I have Delta switch which has another arrestor in it, then to the radio. I screwed an aluminum sheet to my shack table and then a copper pipe onto the back of the table with screws to attach equipment grounding terminals. The radio sits on the aluminum and is…
