The OE-254 is a general-purpose, stationary, broadband, omni-directional antenna used to extend the range of tactical FM radio sets. Under normal field conditions, the antenna will be mast-mounted. Once installed, the OE-254 doesn๏ฟฝt have to be taken down for adjustment when a new frequency band is assigned to the radio net. The OE-254๏ฟฝs technical characteristics are: frequency range, 30-88 mhz; planning range, 57.9 kilometers (36 miles) over average terrain or 48.3 kilometers (30 miles) over difficult terrain; radio-frequency power capability, 35 watts nominal; antenna-erection time (one person), 15 minutes; height when erected, 12.8 meters (42 feet); input impedance to radio, 50 ohms; and weight, 20.4 kilograms (45 pounds).
