DEITY Theos RF Filter

In-line passive filters that sit between your antenna and receiver (or antenna distro) to cut out-of-band energy and protect against front-end overload in busy RF environments. They lower the noise floor, reduce intermodulation artifacts, and help keep links stable when working near other transmitters, walkies or broadcast signals. Built for carts, racks and bag rigs alike, and drop straight into standard 50-ohm signal paths. Four frequency groups are available (U1 through U4), so please make sure customers order the correct group for their region and channel plan.

Deity RF Filters are in-line accessories designed to reduce out-of-band energy and protect wireless receivers from front-end overload in congested RF environments. Placed between your antenna and receiver or antenna distribution, they help lower the noise floor, mitigate intermodulation artifacts, and stabilize links when other transmitters, walkies, or local broadcast signals are nearby—supporting leaner reception and more reliable channel coordination on set.
Built for professional carts, racks, and bag rigs, these passive filters integrate seamlessly into standard 50-ohm RF signal paths and are equally suited to fixed installations or fast location setups. Use them at the antenna input or the distro front end to target problematic interference sources and maintain consistent performance across multi-receiver systems—especially when working with long coax runs or in mixed-RF venues.
