Wow, Ive never really considered splitting the band like that as desirable in an FM antnna, though I suspect that they do decent on the opposite side of the band. I favor 88-92 so that is the one I would tend to favor.
Thanks for the update!
From what I understand APS has some APS 13's in stock now, as well.
My guess is that APS had some requests for custom designs, or their designer had done some one-offs and decided to market them. Since it's difficult to get a Yagi to have consistent broadband characteristics (directionality as well as gain), and Brian Beezley has shown that optimized Yagis can have excellent gain/directivity for their size, I'm not too surprised. Note how closely-coupled the active dipole and first director are and the construction of the matching box; that seems to reflect recent design concepts.
Aside from that, there are a couple of verticals which are tuned for the low end of the band.
As I Live in Columbus Ohio you still need a good FM/AM antenna to pick up some of the fringe stations. Since I have a Radiosophy HD100 tabletop radio. The default dipole antenna is detachable and I have four antennas. One FM Reflect, One Jensen rabbit ears antenna with a gain dial, two Terk AM loop antenna one passive and one amplified. It does a fine job picking up the community LPFM station. Downside is that that there is on direct entry keypad on the unit. It does help that I live on the fourth floor apartment it helps out with TV and radio reception.
