The final disposition of the 42-50MHz slot was to
fixed and land mobile services.
The military also could use the 42-50 Mhz band, as part of their VHF
FM squad radio band, as seen in the zillions of AN/PRC-6 and AN/PRC-10
sets. They pretty much grabbed the band during World War 2, when their
really was no commercial television, and they did not want to give it
back.
