AD-707a Wideband 4-Channel Antenna Divider

AD-707a Wideband 4-Channel Antenna Divider The AD-707a 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. The AD-707a also features a buffered aux in and out for linking additional dividers in multi channel systems without comprising signal integrity. The AD-707a utilizes wide dynamic range and low noise components, advanced circuit design featuring very low inter-modulation distortion and eliminates greatly reduces spurious interference in multiple system usage. System output gain equals to one.

It is compatible with any antennas within its wideband ranges like AT-20 Coaxial Antenna,
AT-70 UHF Ground Plane Antenna and AT-90T UHF Log Periodic Dipole Array Antenna.

The input antenna connector provides power for the optional AT-70B antenna booster and
AT-90R UHF Active Log Periodic Dipole Array Antennas.

  • Optimized for 470~850MHz carrier frequency range and compatible with US and EU telecom regulations.
  • A single AD-707a 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. Besides, through optional booster, it also can be linked to ground plane antenna or UHF wideband log antenna.
  • 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.
