General Description

The Shure UA860V is a passive, ground-reference omnidirectional VHF antenna for use with VHF wireless systems.

Features

  • Greatly improves reception of wireless signal
  • Omnidirectional dipole reception pattern
  • Integrated microphone stand adapter
  • Includes UA8-174-216 antenna, thread adapter, and a 3m (10ft) coaxial antenna cable

Installation

  • Choose a location for installing the antenna that follows the proper guidelines for cabling and antenna placement.
  • Connect the provided UA8 antenna to the top plate of the UA860V.
  • Connect the UA860V to the receiver or antenna distribution system.
  • Mount the UA860V to a microphone stand. For best performance, keep the antenna upright and the grounding plate horizontal.

UA860V Installation

Cable Maintenance

To maintain top performance for antenna cables:

  • Avoid sharp bends or kinks in the cables.
  • Do not deform cables with makeshift clamps, such as bending a nail over the cable.
  • Do not use in permanent outdoor installations.
  • Do not expose to extreme moisture.

Selecting Antenna Cables

Use 50 ohm low-loss coaxial cable, such as RG-8U. Shure offers pre-terminated antenna cables ranging from 6 to 100 feet.

Antenna Placement

Use the following guidelines when mounting antennas:

  • Receivers, amplifiers, and other accessories must be rated for use within the same frequency range as the antenna.
  • Mount antennas at least one wavelength (1.75 m) apart.
  • Keep antennas away from metal objects.
  • Position antennas so there is nothing obstructing a line of sight to the transmitter (including the audience).
  • Place antennas as close as possible to transmitter, such as to the side of the stage (instead of a front of house location).
  • For cable runs exceeding 50 feet (15 meters), an in-line amplifier (Shure UA834) might be necessary to compensate for signal loss.

Important: Always perform a "walk around" test to verify coverage before using a wireless system during a speech or performance. Experiment with antenna placement to find the optimum location. If necessary, mark "trouble spots" and ask presenters or performers to avoid those areas.
