The AD-707 is a professional UHF Antenna Divider designed to allow
up to four UHF diversity receivers to operate from a single pair of
antennas, greatly reducing antenna clutter in multi-system
installations. When combined with an AD-707A Extension Antenna
and an AD-707B Antenna Booster, the AD-707 Antenna Divider provides
optimal signal reception with minimal dropouts or interference.
The AD-707 features the latest in low noise and wide dynamic range
components, plus advanced circuitry designed to eliminate the spurious
interference found in multiple system usage. System output gain for the
AD-707 is equal to 1. The antenna-input connector can be installed
directly to the interior antenna or connected to an optional AD-707A
extension antenna. The input antenna connector provides power for an
optional AD-707B antenna booster.
The AD-707A utilizes a 1/4-wavelength single pole ground-plane
antenna optimized for the 620~960MHz frequency band. It will perform
uniformly throughout the receiving band without modifying the antenna
length and reflects side-band signals similar to a band-pass filter.
The antenna impedance is 50 Ω and can be matched with any 50 Ω coaxial
antenna cable. The ground-plane antenna allows stable reception without
spurious emissions. The AD-707A contains 2 antennas and a pair of MS10
antenna mounts for securing the AD-707A to a wall or ceiling.
The AD-707B consists of a pair of receiving signal boosters
operating between 620~960MHz which offer 13dB of gain to compensate for
antenna cable loss or for when extra range is required. They will
noticeably improve the S/N ratio, increasing the operating range and
stability of received signals.
