An antenna of some physical size will indeed have gain increasing with
frequency. There is some justification, a 1 GHz antenna being reasonably
small, for assuming that antennas will have similar sizes -- and increasing
gain -- above 960 MHz. However, I suspect that the original limit was
simply an extrapolation, not many users existing there to be affected by
Part 15 devices, from the limit _below_ 960 MHz.
