The SF1 Active Directional (sharkfin) Antenna is a broadband UHF receive antenna designed to
improve range and reliability for professional wireless systems. It covers 470–960 MHz with a
directional 60° optimal pickup angle and linear polarization to focus reception where you need it.
An integrated amplifier provides –9 dB to +21 dB gain in 1 dB steps (with overload indication),
while unpowered operation delivers typical 6 dBi passive gain for flexible deployment. The
enclosure is IP54-rated for splash and dust resistance, suitable for location film and theatrical
use.
Connection and power are straightforward via a 50 O BNC feed; when your receiver or antenna
distributor supplies 12–16.8 V DC bias, the SF1 runs in active mode (approx. 12 V/90 mA). A
clear gain display with +/– buttons simplifies on-site adjustment, and a mounting base with 3/8"-
to-5/8" threading supports common stands. Key RF performance figures include OIP3 39 dBm
and max RF input 30 mW, helping maintain signal integrity in complex RF environments.
