5.5.1 EQUIPMENT AND SOFTWARE REQUIRED FOR ANTENNA TUNING AND TESTING
• 1 x Antenna Tuning Probe with cable (Magellan Antenna Tuning Kit)
• 1 x RF Trimming Tool (Magellan Antenna Tuning Kit)
• 1 x Universal Digital Voltmeter (to measure DC voltages between 1 and 15 volts)
• Magellan ReaderManager software– V2.05 or better
• 1 x Tag (fully powered tag)
Antenna Tuning Kit: Antenna Tuning Probe with a cable and RF Trimming Tool
5.5.2 TUNING INSTRUCTIONS
Connect the Antenna Tuning Probe terminals to the voltage and input terminals of the digital voltmeter.
Set the voltmeter to measure a DC voltage range greater than 10 volts.
Place the Antenna Tuning Probe in the center of the antenna.
Using an RF trimming tool adjust the tuning capacitor on the antenna for maximum voltage as measured by
the tuning probe.
5.5.3 OPTIMISATION OF ANTENNA PERFORMANCE
If maximum read distance is important for your application then the antennas have to be protected/shielded
from interference using appropriate mounting material, and then tuned to maximum voltage.
If maximum read distance is not an issue the antennas can still work e ectively even if not tuned to maximum
voltage, but the e ect will be reduced read range.
