Hello men. I wonder if anyone knows the difference between the HD7698P and the HD7697P? It looks like the range and frequency response are the same. Thoughts? Thanks fellows!

Jonny,

In simple terms, the more elements added to an antenna increases its "focus" for more signal strength or 'gain' ... so if you have a weak channel and your TV requires a stronger signal, that is one way to achieve it. Narrow-beam reception, something like a pinpoint driving light on a rally car.

On the other hand, the more elements added to an antenna reduces its ability to receive a variety of channels that are transmitting from different but nearby sites, such as on adjacent mountain tops. (both sides of the road)

So, in some situations a wide-beam rally-car foglight (fewer antenna elements) is a better antenna choice.

You are correct on their Frequency Reception, in that they both receive VHF-hi and UHF, but...
There is a difference in their "range", that being the...

HD7697 is 50 mi UHF and 60 mi VHF-hi with 53 elements, and the
HD7698 is 60 mi UHF and 70 mi VHF-hi with 64 elements.

That makes the 7698 a little more sensitive, which equates to the increase in the range numbers as Jim has pointed out.
