[BF1] Antenna Overview and Field Applications
An overview of the Deity BF1 UHF antenna: who it is for, what it includes, its omnidirectional polar pattern, and real-world field applications.
The Deity BF1 is a universal antenna for any UHF wireless system, at home on a sound bag or built into an audio rack. This overview walks through who it is for, what comes in the kit, how its omnidirectional pattern behaves, and the situations where a remote antenna earns its place on set.

What is the BF1?
The Deity BF1 is a universal antenna for any UHF wireless system.
It can be used on a sound bag setup or integrated into an audio rack system.
Who is this for?
If you’re someone who captures media for houses of worship, comedy clubs, live music venues, or you’re a production sound mixer in the TV/Film industry, the BF1 is for you.


What does it come with?
⚫ 2x BF1 Antennas
⚫ 2x SMA-BNC Cables
⚫ 2x BNC Cables
⚫ 2x Antenna Clamps
⚫ 1x Neoprene Carrying Case

Polar Patterns and Polarization
The BF1 is an omnidirectional antenna. There is some rejection on the top and bottom of the antenna but think of it as an omni.
Wherever your transmitters are on set, your antenna will “see” them. The BF1 is also passive, meaning you can use it on your transmitter for IFB and IEM systems.
Other Specs
⚫ Passive
⚫ 470 MHz, 1 GHz range
⚫ 2.2dBi Gain
⚫ 50 Ohm BNC
⚫ 1/4″-20 mount
⚫ Composite Fiberglass
⚫ 7.4″ / 95g


Use case
One major benefit of using the BF1 is that it lowers the total number of antennas your devices need to function. This greatly reduces the chance of the antennas interfering with each other and compromising your transmission.
Additionally, because this is an external antenna, you can remote it in problematic shooting situations such as transmitting through walls or metal structures.
