Antenna Placement

Use the following guidelines when mounting antennas:

Antennas and receivers must cover the same frequency range.

Mount antennas at least four feet apart for optimal diversity.

Position antennas so there is nothing obstructing a line of sight to the transmitter (including the audience).

Positioning Antennas for Diversity Reception

The UA864 is a polarized antenna and must be oriented correctly to optimize reception for each transmitter type. Position the antennas using the follow- ing guidelines:

Note: Use the gain switch as an indicator of the antenna orientation.

Handheld and Bodypack Transmitters (vertical)

Boundary Microphones (horizontal)

Mixed Transmitter Types (vertical and horizontal)
