But now you're comparing apples to oranges. He was originally talking about having the repeater in a comm van. Comm vans (& trailers) are intended to be mobile and placed either AT or very NEAR the problem area. You are talking about putting a relay at or near the problem area & having the comm CENTER (not the comm van) back at the long established headquarters location.
