FINALLY found this thread
OK, using a program/ap like www.antennaweb.org
Locate the direction from your campsite to the local transmit tower.
You can switch to "satellite" view to actually find your site and aim along the line to the tower to find what to aim your antenna at.
Remember, newer antennas are DIRECTIONAL and the white amp box/short elements on the head must point TO the towers and the "wings" must be like the wings of an aircraft and be 90 degrees to the tower heading.
Once you are aligned, then you need to rescan the TV's tuner to find your channels. ALWAYS turn booster on (light ON in faceplate) when using roof antenna and then scan.
Use TV setup and always select "AIR" or "ANTENNA" depending on TV model when scanning.
With an iPhone/iPad you can use the free "TV Towers" App.
