The UHF portion of the Element is roughly on par with the DB2e. On high VHF, the C5 outperforms the Element by a small margin. IIRC, the modeled gain on high VHF was somewhere around 7 dBi (+/-) and on UHF was around 9-9.5 dBi.

I don't know of any technical reason that would support the claim of an LPDA doing better in fringe areas or with weak signals.

Yes, the Element is a modest gain antenna that does have a wide beamwidth, it's only about a meter long and it's a dual band design so there isn't a whole lot of space for multiple elements. I don't have the tech data handy ATM although I can get it on Monday.
