470-952 MHz, depending on region
Working Range
150 m (500 ft.), under typical conditions
500 m (1600 ft) line-of-sight, outdoors
for a single system
NOTE: Actual working range depends on RF signal absorption, reflection and interference
Audio Frequency Response
40 – 18,000 Hz,(+1 dB, –3 dB).
NOTE: Overall system frequency response depends on the microphone element
Gain Adjustment Range
UR2: –10 to +20 dB
Modulation
FM (45 kHz max. deviation), compander system with pre- and de-emphasis
RF Power Output
See table above.
Dynamic Range
