Actually, the UHF TV Band is the provision for expansion. There are secondary
services that have spectrum allocations in that band.
The gaps in the VHF TV allocations is so that useful spectrum isn't
completely allocated to the broadcasters.
There are gaps between channels 4 and 5, and channels 6 and 7.
The first gap spans 72-76 MHz, and the second, 88-174 MHz. Your posting
seems quite unclear to me on that point.
You may note that the first gap is allocated to Radio Control and some
Land-mobile services. The second gap is allocated to FM Broadcast, AM
Aircraft, and FM Mobile services.
The FCC tries always to ensure an equitable distribution of available
spectrum.
