/diy/ - Do It Yourself

Hello friendly /ham/ers,

I'm starting the basic step before installing antennas on my rooftop: Grounding to earth.
My question is quite simple: Do I need to draw a distinct line away from the home's grounding line ?

Having read some comments about lightning, do you set up some circuit breaker between antennas and its receiver to cut everything easily under storm ?

I live 30m away from a lightning arrester that culminates at 25m. In Theory, it has some thorium spike on it, nah ?

and maybe a last question. I plan to set up some antennas near of an already installed Starlink's Dishy, which crawl between 10-12Ghz. Could I experience some noise problem ?
