AD-707
UHF Antenna Divider System for UHF Diversity Receivers

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.

AT-90T UHF Unidirectional Antenna: This product is a professional UHF directional antenna covering the RF bandwidth from 600 to 1000 MHz and provides an additional 6 dBi of gain. The AT-90T is a directional antenna providing superb receiving and transmitting performance when targeted in a specific direction. This product is suitable for indoor or outdoor all-weather applications.

AT-90R UHF Active Unidirectional Antenna: This product is a professional UHF directional antenna covering the RF bandwidth from 600 to 1000 MHz and provides an additional 6 dBi of gain. The AT-90R enhances reception coverage and improves ranges when targeted in a specific direction. The built-in 1.6dB low-noise analog and 13dB low-noise amplifier to compen-sate for signal loss from longer coaxial cable runs. This product is suitable for indoor or outdoor all-weather applications.

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.
