Instalation

Antenna needs to be installed on a metal surface, performance will vary unless groundplane is stable. Minimum suggest groundplane is 18” x 18” however, the antennas can be tuned to work on smaller

groundplanes

Reference Testing

• Performance of ACA miniBAR, WTT, MSA/BOH/Ribbit/Solar Wedge* compared to a popular low profile reference antenna**

• Stelperform comparison on vertical and horizontal metal surfaces – 40 byte messages sent every minute to satellite – max 60 messages per hour

• *All part of the same development now resulting in the Solar Wedge range and the RIBBIT

• **Popular low profile antenna is based on a ¼ wave design – not a ½ wave

Latest relative test results from Webb JBG

• 12.1% improvement on Time-to-live for Solar Wedge/Ribbit vs. Popular Antenna on 13-byte msgs

• We measure 45% improvement for Solar Wedge/Ribbit vs. Popular Antenna on Acquire Burst success

• We have measured a 5 dB improvement in gain for the Solar Wedge/Ribbit, confirmed using an array of attenuators and unity gain antenna
