MIPRO AT-90W UHF Multi-function Directional Log Antenna
The AT-90W is a UHF 470–1000 MHz log-periodic antenna with 4–6 dBi gain, offering strong directionality and interference rejection. Its adjustable 0–12 dB booster ensures stable long-distance reception for outdoor events and touring systems.
- Dual-mode design supports both transmission and reception in the UHF 470 – 1000 MHz frequency range.
- 4 – 6 dBi gain enables efficient signal performance over medium to long distances.
- Log-periodic directional structure delivers excellent front-to-back ratio and side-lobe suppression, focusing on target signals while minimizing rear interference.
- RX Only port features a built-in adjustable booster (0 – 12 dB), powered via bias voltage, to enhance reception sensitivity and stability.
- Compatible with MPB-30 antenna booster and AD-12 antenna distributor for extended system coverage and optimized wireless performance.
AT-90W 為 UHF 470 ~ 1000 MHz 對數定向天線,具 4 ~ 6 dBi 增益與 0 ~ 12 dB 可調式強波器,適合戶外與巡演系統長距離接收。
- 發射與接收兩用設計,適用於 UHF 470 ~ 1000 MHz,具 4 ~ 6 dBi 增益,適合中長距離高效率收發應用。
- 採對數週期定向結構,具良好前後比與側波抑制能力,集中接收特定方向訊號,有效降低背向雜訊干擾。
- RX Only 接頭內建 0 ~ 12 dB 可調式強波器,需由具偏壓供電設備啟動,有效提升接收靈敏度與穩定性。
- 可搭配 MPB-30 及 AD-12 使用,擴充接收距離與系統覆蓋範圍,提升整體傳輸效能。
