Like New! UHF-AM Forward Air Controller Radio, Predecessor to the PRC-41. With accessories-- bag, spare modules, spare RT, and steel-pot-mounted antenna.... From Dave Ross' Website (RIP, Dave!): The PRC-14 was intended to give the groundpounders a way to talk directly to aircraft using the new UHF AM band. In the late forties, U.S. military aviation began a migration from the shared VHF AM band of 100-156 MCs to the strictly military UHF AM band of 225-400 MCs. This little critter was one of the military's first attempts to get a portable radio to work in that UHF AM band. The set wasn't intended to be operated in the canvas - it was instead strapped onto the lucky grunt with the power supply on his back and the transceiver on his chest. The antenna was tightly clamped onto the steel helmet - the radiation pattern modeling of a 1/4 wave vertical atop a GI helmet is left as an exercise for the reader...
