In principle, the “academic” border between UHF and VHF is 300 Mhz. However, the USAF uses frequencies below 270 Mhz and above 360 Mhz, and appears to use the same name (UHF) for both bands. (The B-52 EWO Capt. Goduto operated the 360 Mhz HF radio). It is notable that the VHF (radio) reception by the B-52 was not affected, nor the transponder affected, since it was used to communicate with RAPCON during the transmission failure. Also, the B-52 radar detection was unaffected.
