I'll weigh in on this, because I've been with Scott on many of those trips - yes, he does have a special tool that gets him access to the cable that's normally tough to get out from the wall.
Locally, 20 miles out from the local antenna farm (Cleveland, which is in suburban Parma, OH):
Analog: A sparkly signal from WKYC/3 (NBC), a less sparkly but not quite perfect signal from WEWS/5 (ABC), and a clear signal from WJW/8 (now Fox, ex-CBS). All the market's UHFs were fine, for the most part.
Digital: Solid, clear signals from WKYC/3 (now on RF 17), WEWS/5 (now on RF 15), and nearly all the market's signals that were on analog pre-2009 (17, 23, 25, 43, 49, 55, 61, and 67, which is now PSIPing as its RF channel 47). A couple of these break up very occasionally, but are solid 95-99% of the time.
The problem children are the two VHF stations, WJW/8 (went from RF 31 pre-transition to RF 8, and is in the early process of trying to go back to 31) and WOIO/19 (CBS, RF 10 before and after, and on topic for this board, gets a LOT of cross-Lake Erie problems from CFPL/10 in London).
19 has a CP for an RF 24 digital translator in the southern part of the market, which will solve its reception problems here at the OMW World Headquarters(tm), as would a full-power RF 31 facility for WJW.
I am using a modest UHF indoor antenna for all of this. Overall, aside from the 8/19 problems, I'm much happier in the digital era.
