One secret is that the UHF driven element is a tetrapole, in the original version of the 751.

RCA likes to change the design in mid stream without changing the model number, usually to meet a price point with the loss of some performance.

Another secret is that the VHF section is an LPDA.

Another secret is that it is an original Winegard design.

And with so few elements on the ANT751, it really is quite a good performer across the TV frequencies.
A lot of good reports from users in strong signal areas.

Any idea what that gap is for?
