VEST POCKET TRANSMITTER
FOR USE IN CROWDS _ A waistcoat pocket transmitter, designed primarily for programme work in crowds in which the announcer must move quickly to any given point, has recently been perfected. It weighs less than a pound, and is contained, apart from its two lOin aerial rods, within a 3in cube, and so is easily grasped in one hand. Current is derived from a small 90-volt B battery, and the transmitter has a power output of 2 watts, ensuring a range of four miles. The transmitter is the result of exhaustive tests with short wave apparatus, and works on the oOO.OOOkc wave band. It has shown a remarkable capacity for penetrating through intervening structures.
