Why do you need a studio?
If this is completely non-commercial and you have an amateur license you could probably use AREDN as a backhaul instead of HaLow. We've gotten wifi going from a panel in Elysian up to Wilson on AREDN.
100w from the Verdugos should be pretty substantial. I regularly make 70cm FM contacts on 446.500 from Elysian Park down to San Diego at 5w.
Broadcast radio is, with caveats, prohibited on amateur radio.
You're not allowed to "broadcast" (with a few exceptions) or play music with an Amateur licence.
I would be really surprised if we are allowed to use AREDN.
We need a studio to be able to do live radio shows. Currently our hosts have to pre-record and submit through an online dashboard. The goal is to have a live studio in Shadow Hills where hosts can do their shows, bring on guests, take calls, etc.
