Important Notes

• Active mode requires 12–16.8V DC bias from a compatible receiver or antenna distribution system.
• Use gain to compensate for calculated coaxial cable loss; excessive gain can amplify interference and ambient RF noise.
• Aim the antenna toward the desired coverage area and keep clear line-of-sight to the transmitters where possible.
• Mount antennas high, keep them away from metal objects and space antennas at least 1m apart where possible.
• Always perform a walk-around test before a recording, speech or performance to confirm coverage.
