@BillRM,
Thanks, Bill, for the explanation. Who knew (aside from you)? I guess we didn't have one of those.
In the very early days of TV, most of the broadcasts came from downtown. I guess we just pointed the antenna south and hoped for the best.
Off topic, but speaking of antennas, I'm reminded of the time I went up on the roof and moved them all around.
Wasn't I the little angel?
