nextraCOM TTR-AGC 8230G - Bi-directional Transmission Trunk Amplifier
	It is applied to extending of bi-directional (or can be reserved) transmission main trunk to signal compensatory use. Pre-build low-noise module, and final-class is power doubler module,with AGC control , all these are Philips and Motorola’s products. One input and two outputs have over-current protection (fuse switch) and output branch or distribution can be switched conveniently. High-reliable switch power and strict anti-thunder character insure steady and continuous work.
