Tuning the tv antenna

Get yourself one of these.

Mine is plugged into an open TV port on my distribution box. I just turn it on and hang it outside the cabinet so I can see from upstairs while I am turning the antenna.

Rotate antenna until I have the maximum strength, THEN I do the channel scan on the TV. Work great.

Usually only need to do it once unless I am between TV towers and looking for a specific station.

Some TVs now have a signal strength indicator. Look real good through the menus - sometimes they are buried pretty deep. If you find one, rotate the antenna slowly as there is usually a delay in the indication.
Broadcast stations are frequently (but not always) located in the same location; to get the first one so you can orient the antenna, do the auto scan and stop it after the first channel is indicated. The TV receiver will usually allow you to abort the auto-scan and receive the first signal you get. Use this as a "beacon".

The next method (and probably the best) is get out a map and compass and orient the antenna toward the closest major city.

The typical RV antenna is directional broad side to the long axis of the antenna; and toward the side away from the support mast.

I've really never noticed a major difference. Silly question and I don't mean to insult, but is your booster turned on? I've moved my antennae around several times and it really didn't make any difference.
