High Definition TV

It is common knowledge that the best way, probably the only way, toreceive 1080pixels TV in North America is ODA. I just installed a TV Antenna and I am pleasantly surprised at theresults. A signal that before would give a very noise picture,digitally, will give an excellent picture.But I have a problem. How does one orient the antenna for the bestsignal. Before we would rotate the antenna for the strongest signalbut with digital signals the signal is on or isn't there. Rotatingthe antenna and parking between the 2 "no signal" positions, is oneway but I would prefer to adjust it to the maximum signal. There is probably an agc signal that can be tapped inside the rx butthat I would like to do after the warranty expiresAnother puzzle I have is that I installed an antenna that is no morethan 40 x 50 cm with 6 elements and claims to have a minimum gain of28 dB from 40 to 890 MHz.Four of the directors are inside of plastic that may have inductors toincrease their electrical. The main dipole goes inside of a box thatinclude the electronics to rotate the assembly and may have an rfamplifier.Comments please.John
