Product Description

Avlex AD-708 UHF Four-Channel Auto Gain-Control Antenna Divider 

The AD-708 is compatible with Mipro’s Series 7 wide-band receivers or any other true diversity receivers that operate within its frequency range of 470 to 850MHz . Four UHF diversity receivers can be operated from just a pair of antennas, greatly reducing antenna installations clutter and increasing receiving range, signal integrity and efficiency.
MIPRO’s AD-708 integrates an innovative Auto Gain-Control system that automatically detects, controls and precisely compensates for signal loss of antenna cables when used with the MPB-30 gain-controllable antenna booster. The AD-708 solves complex antenna system installation issues, optimizes signal reception and system performance without worrying about calculating signal-loss of antennas, cables, and the specifications of boosters.

The AD-708 also features a buffered aux in and out for linking additional dividers in multi-channel systems without compromising signal integrity. The AD-708 utilizes wide dynamic range and low noise components, advanced circuit design featuring very low inter-modulation distortion and greatly reduces spurious interference in multiple channel applications.

FEATURES:

• Optimized for 470~850MHz carrier frequency range and compatible with US and EU telecom regulations.
• Auto Gain -Control automatically detects, controls and compensates for antenna cable signal loss when used with MPB-30 boosters.
• A single AD-708 supports up to four UHF diversity receivers from just a pair of antennas, greatly reducing antenna installations clutter and increasing receiving range and efficiency.
• Adopts the latest high dynamic range and low noise component, advanced circuit design featuring very low inter-modulation distortion and eliminates the spurious interference in multiple system usage. System output gain equals ~1.
• 2 sets of antenna input/output connectors and 2 sets of 4-channel antenna output connectors for directly connecting to 4 sets of diversity receivers. The antenna input connector can be fitted with whip antenna or coaxial antenna of appropriate frequency band, it also can be linked to ground plane antennas or UHF wideband log antennas.
• The output connectors can be linked to the input connectors of another antenna divider for extended antenna distribution.
• The input connectors provide DC bias for the antenna boosters or active directional antennas.
• Booster power indicator to detect the linkage of booster.
