3 Counties coverage, are you referring to Old Saddleback (Santiago)?
Don't recall the site name, If I dig, I can come up with coordinates.
A buddy named "Bob" had a 2 meter repeater there. Eyeshot of San Bernardino, Riverside, LA. Overlooked all of east LA.
So, What Bob did was install a translator, UHF in, any mode. Output mode you selected with touch tone (6 I think)
The 11 meter part was from a Pathcom. Filtered output driving a 100 watt+ PA. That went to a "droopy drawers" antenna about 40 foot up.
Frequency span went from 26.400 to well above 27.470. Worked exceptionally well after the band go quiet. even from So Bay.
