The Viviana Pebble is an innovative antenna designed for body-worn wireless transmitters used in film, television, theatre and corporate production.
In traditional wireless systems, range is often limited because the human body absorbs and blocks RF energy. When a standard whip antenna is placed close to the body, much of the transmitted RF energy is directed into the body where it is absorbed and dissipated.
Viviana Pebble solves this problem using patented BodyWave technology.
The rear surface of Viviana Pebble acts as a ground plane, directing RF energy away from the body and the patented technology of the antenna allows signals to ‘creep’ around it rather than into it.
This allows the signal to propagate far more efficiently into the surrounding space.
The Viviana Pebble features:
- Improved usable range for existing wireless systems
- More consistent signal strength
- Greater reliability when worn close to the body
- Provides a much better 50 Ohm resistive match across the full band,
ensuring optimal power transfer from any transmitter
- Rugged, low-profile design making it practical for real-world production
use
Because RF energy is directed away from the body, the transmitter operates more efficiently compared with traditional whip antennas worn against the body.
Viviana Sound Solutions offers a range of accessories designed to mount Viviana Pebble securely and discreetly, such as the Viviana Straps Extreme.
The Viviana Pebble provides the greatest improvement in situations where the body would normally block the transmitter antenna.
Typical examples include:
- Open outdoor environments
- Large studios or stages
- When transmitters are worn under clothing or costumes
- When talent frequently turns away from the receive antennas
In these scenarios Viviana Pebble can significantly improve usable range and signal stability.
