AC and Solar Powered

Long-Range Wireless Repeaters work in much the same
way as the Vantage Pro2 Wireless Repeaters (# 7626, 7627),
but extend the range and reception between a transmitting
station and a receiver by up to 10 times that of the standard
wireless repeater.

The Long-Range Wireless Repeater (US Version only, see note below) works in conjunction with two external
antennas (# 7656, 7660), one for receiving and one for transmitting, to retransmit data over greater distances than a
wireless repeater with the standard dipole antenna. Transmission distances vary depending on the antennas selected
and how they are used in a network. The Long-Range Wireless Repeater can listen for up to eight different transmitter
signals and can pass those signals on to another repeater or to any number of receivers.

AC-powered long-range repeaters (# 7653) include an AC-power adapter and battery. Solar-powered repeaters
(# 7654) include a solar power panel, regulator and battery. The external Omni-direction (# 7656) and Yagi (# 7660)
antennas used in conjunction with the long-range repeater should be p urchased separately.

Note: Davis Instruments sells FCC Type approved ante nnas in conjunction with the long-range repeater. These antennas are available for US customers

only. US customers must use these antennas. O verseas customers are responsible for procuring their own long-range antennas for use with the
Long-Range Wireless Repeater that comply with local regulations. These transmitting ante nnas have an 8 dBi gain limit (the receiving ant ennas have
no gain limitations). There is a limit of no more than four transmitter IDs to comply with the EN 300 220 regulation for all overseas customers.
