Viviana Pebble
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 result is:
Improved usable range
More consistent signal strength
Greater reliability when worn close to the body
Because RF energy is directed away from the body, the transmitter operates more efficiently compared with traditional whip antennas worn against the body.
Technical Highlights:
Frequency range of tested unit: 590–630 MHz
Provides a much better 50 Ohm resistive match across the full band, ensuring optimal power transfer from any transmitter
Designed for on-body use, minimising detuning and signal loss
Rugged, low-profile design making it practical for real-world production use
Available to order with a range of custom patch cables to suit major wireless mic brands
“This antenna works with the body, not against it — preventing the huge losses when the TX antenna is on the wrong side.” – Pyers Easton, CEO, Raycom
Where Viviana Pebble Performs Best
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.
Where the Difference May Be Smaller
Viviana Pebble is designed to solve the specific problem of body absorption.
If that problem is not present, the improvement may naturally be less noticeable.
Examples include:
When the transmitter antenna is not close to the body
Indoor environments with strong RF reflections
In these situations Viviana Pebble will still perform well, but the improvement compared with a whip antenna may be smaller.
We hope you enjoy many years of improved range and reliability with Viviana Pebble.
