PRODUCT OVERVIEW
1-5
Part No. 001-4090-101/102
FCC/IC Rule: The output power is not to exceed 1.0 watt and the EIRP not to exceed 6 dBW if the hopset
uses 50 or more frequencies. A sample calculation is provided below.
Sample Calculation: Yagi Antenna: 10 dB Exceeds 6 dBi gain by 4 dB
Cable Loss: 1 dB
Integra-H output must be reduced by 4 dB (plus 1 dB to account for cable loss)
30 dBm - 4 dB + 1 dB (cable loss) = 27 dBm at antenna port of Integra-H
after 1 dB loss through cable: 27 dBm - 1 dB = 26 dBm input to antenna
Result: reduction of 4 dB

SAFETY NOTICE
The Integra-H uses low power radio frequency transmitters. The concentrated
energy from an antenna may pose a health hazard. People should not be in front of
the antenna when the transmitter is operating.
