Lightning arrestor neccessary?

self.HeliumNetwork1m ago
Iv had my miner installed for about a month now. Im going up from $12 down to $2. My set up is a directional 8dbi antenna sitting above my roof say around 30 feet high with a 30 foot LMR400 cable. Iv done my research and Iv spent the money where needed. Is there static build up where I need a lightning arrestor? I found that 98% of miners do not use this. Am I missing out on something?
