history of vhf radio
A VHF ocsillator is a very high frequency ocsillator (30-300MHz). It oscillates (swings back and forth) at a VHF frequency.
While both use high frequencies that are line of sight range only, the cellphone connects to a cellular network of transceiver antenna towers that are interconnected (via either landlines or microwave links) permitting cellphones at practically unlimited distances to communicate.
