05-4186A01-eNETL2TUV_Manual_RevD.doc 1 Important Information 1.1 RF Exposure Professional installation required. The radio equipment described in this guide emits radio frequency energy. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Do not allow people to come closer than 2.07 meters (6.79 feet) to the antenna when the transmitter is operating in indoor or outdoor environments.
05-4186A01-eNETL2TUV_Manual_RevD.doc 2 Introduction The eNETL2T/U/V is an RF power amplifier designed for use in the 210–270 MHz frequency range at up to 40 Watts. It is intended to serve as a 100% duty cycle amplifier for MDS entraNET 220 and TD220 radios operating in point-to-multipoint repeater or base applications. 2.
