I envy your ‘ruralness’ but not your communications/radio/TV difficulties.
You need a TV antenna up high on a tower. And even that is no guarantee of acceptable performance.
My husband’s radio antenna is on a Rohn (sp?) tower and does great but no way he’d let me put a TV antenna on it. It’s one of those that has a metal base plate anchored in four feet of concrete, cranks down, and will lay down in the yard to work on. I hate that thing.
