Deity SF1 Directional Shark Fin Antenna

The SF1’s wide frequency range and robust design make it versatile for different wireless systems, including Deity’s THEOS ecosystem and other brands. Its weather-sealed housing ensures reliability in various conditions, and the metal mount brackets provide secure installation.

SF1 is built to win back signal quality in messy RF. Its directional panel and ~60° optimal pickup angle let you point coverage at the talent and ignore the noise floor that lives off-axis—handy on festival stages, crowded corporate ballrooms, and RF-dense backlots. Keep line-of-sight, mount high, and space diversity antennas at least a wavelength; do a quick “walk-around” and you’ll know exactly where your wireless pickup zones are before the show rolls.

Long cable run to the cart? Dial in just enough active gain—SF1 gives you −9 dB to +21 dB in 1 dB steps with a bright readout, so you can match the line loss you’ve measured instead of guessing. If the front end starts to saturate, the red overload indicator tells you instantly; back the gain down and preserve headroom rather than amplifying the entire RF neighborhood. And if there’s no DC bias available, SF1 still pulls its weight as a passive panel with 6 dBi gain.

From theater to house of worship to TV sets, the SF1 covers 470–960 MHz, so your kit doesn’t need to change when the venue does. Standard 50 Ω BNC connectivity drops right into pro distros and low-loss coax; an OIP3 of 39 dBm helps keep dynamic range intact in crowded spectrum. Power is frictionless—just feed 12–16.8 V DC bias from your receiver or distro and you’re live.

Rain on the sideline, dust on location, or a week of load-ins—SF1’s IP54 rating and −10 °C to +55 °C operating range make it a safe pick for real-world crews.

The slotted design also allows wind to pass through it, preventing it from turning into a sail.

SF1 is designed to compensate for what your cable is taking away—nothing more, nothing less. Use the attenuation table as a starting point, then trim gain to suit the environment; don’t assume “more” equals “better,” because excess gain boosts interference and ambient RF right along with your signal. The result is a cleaner link, longer useful range, and fewer surprises mid-take.

The SF1 mount features a 3/8" Locator Pin design that prevents twist and turns when trying to mount it accurately. The all metal CNC mounting hinge accepts both 3/8" and 5/8" via an adapter.
