I didn't word that very well.
If you have stations in different directions, one north and another west that are receivable, you have to mount your OTA antenna on a rotator to move it from north to west when you want to view the other OTA station.
Back in the "good 'ole days" when TV was analog and most every station was VHF, we lived in a small town in SE new Mexico that had 3 "local" stations, I use quotes because one of the towers was in town (ABC ch 6) but the other two were 51 (CBS Ch 10) and 73 (NBC ch 8) miles away.
Everybody had a fairly tall guyed push-up mast on top of their house and could pull in all three stations.
We had a 5 section push-up guyed mast with the Finco antenna pictured in my avatar on top and we had a rotator on it so we did not just have to point the antenna north for CBS and NBC out of Roswell, but we could point it NE and occasionally pick up Lubbock stations from 170 miles (very fuzzy without an occasional boost from tropospheric ducting) or turn the antenna SE to get stations out of the Midland/Odessa area. We didn't even have coax, all the downlead was twisted twinlead antenna wire, which we recently have learned is really lower loss than 75 ohm coax, but that is another tale for another time.
