VHF ONLY 2METER TRANSCEIVER

The Icom 2100 is likely referring to the Icom IC-2100H, a rugged 2-meter (144-148 MHz) FM mobile transceiver offering 55, 25, or 10 watts of output power. Key features include a durable design built to MIL-STD shock and vibration standards, an alphanumeric display for memory channels, and a versatile scan function. It requires a 13.8V DC power supply, has a 50-ohm SO-239 antenna connector, and measures approximately 140(W) x 40(H) x 180(D) mm.
