I know exactly what you are talking about , John. The "reception lobes" of the antenna just narrow, i.e more directional. This is good and bad. It is good when you are pointing at the transmitter tower, a bit stronger signal when you are in a congested area. The actual signal strength gain is minimal.
The Bad,... when you are searching, in the channel search mode, for available signals in the area, it may not pick up many stations that may very well be usable. That is after turning the antenna and search agaiin.
I just installed a new Sensor antenna (plain) yesterday but did not opt for any highly-directional wingman option..
FWIW, TV watching is not my main concern, it's just a habit.
Oh well, my 2cents worth.
