- TX/RX shared design allows use as a TX antenna when no bias power is applied.
- High dynamic range amplifier design helps reduce RF overload and intermodulation interference in multi-channel wireless systems.
- RF overload LED indicator allows quick confirmation of RF signal overload conditions.
- ±45° adjustable mounting angle allows flexible positioning for optimal RF reception performance.
- IP65-rated enclosure is suitable for indoor and outdoor installation applications.
- Compatible with microphone stands and mounting brackets for flexible installation applications.
AT-90A is a UHF 470–1000 MHz wideband active directional antenna with 4–6 dBi gain and a 3 dB beam width of 75° vertically and 130° horizontally. Its directional pattern focuses RF coverage and helps reduce side and rear interference.
The built-in low-noise, wideband linear RF amplifier provides +12 dB, +6 dB, 0 dB and -6 dB gain settings when DC 8–18 V bias power is supplied through the coaxial cable. The TX/RX shared design, RF overload LED, ±45° angle adjustment and IP65-rated enclosure support multi-channel and fixed installations. Without bias power, it operates in 0 dB BYPASS mode.
