There is no such thing as a "Digital" antenna.

Yes, but ....

Your standard "old style" TV antenna effectively combined the main signal
with "delayed" versons of the same signal. (The "delay" was on the order
of nano seconds.) Since a lot of the information is a digital signal is is
subtle phase shifts ...

There are "bed spring" UHF antennas which combine signals from several
elements with each element seeing the same phase.


Hi,
Right, antenna does not know what signal it is carrying. Antenna is
designed for gain. B/W and F/B ration based on operating RF.
