164-165MHz 169-170MHz VHF170 5W Channel Selective Repeater with 8 Channel Carriers cover a large area with strong signal system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low‐power signal from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
System manufacturers and designers will never guarantee, and it is impractical to expect, 100 percent coverage. It is impossible to guarantee 100 percent coverage in any city. There is always some corner of a building that a radio system does not cover. The problem with no coverage from a trunked system is very different from a simplex area. In a trunked system, no coverage means no communications.
Frequencies available include 400MHz UHF, 700MHz, 800MHz, and 900MHz. Please contact us with your additional frequency requirements.
