URSA Foamie Flex – Flexible Antenna Savers

Improve RF Signal and Protect Your Wireless Antennas

URSA Foamie Flex is an innovative accessory designed to boost the reliability and performance of body-worn wireless bodypack transmitters. It acts as a flexible spacer and barrier, creating the necessary distance between the transmitter's whip antenna and the talent's body or damp clothing. This simple but effective foam sleeve prevents RF signal detuning and loss, particularly in high-humidity or high-movement environments.

It's the perfect solution for preventing 'body blocking' and sweat-related signal degradation on film sets, in television studios, and across theatrical stages.

Key Features and Performance Benefits

• RF Performance Improvement: The primary function is to space the antenna away from the body, preventing the detuning effect that occurs when an antenna is pressed directly against skin or damp wardrobe. This leads to a more consistent and reliable RF signal.

• Sweat Barrier: The soft foam acts as a protective barrier, reducing the effect of sweat and moisture on the antenna's performance, thereby mitigating sweat-related range loss.

• Comfortable & Discreet: Made from soft, lightweight, and flexible foam, it remains low profile and comfortable for the talent, easily hiding under costumes.

• Universal Compatibility: Simple slide-on application allows it to fit easily over whip antennas of all types.

• Customisable Length: At $13~cm$ long, the foam can be effortlessly cut to size using scissors for use with shorter antennas or specific rigging requirements.

Why URSA Foamie Flex?

Antenna detuning and RF loss are two of the biggest headaches in location and live sound. By ensuring the antenna is held consistently away from the performer's body and protected from sweat, the Foamie Flex ensures that you get the most out of your wireless gear. This small addition provides a huge boost to signal reliability and is an indispensable part of a robust rigging kit.
