SpeedNet Radios must be installed by a professional, in order to comply with FCC Part 15 radiated power
limits. Only antennas supplied by S & C Electric company may be used with the SpeedNet Radios.
The FCC mandates that Effective Isotropic Radiated Power (EIRP) may not exceed +36 dBm. This is
equivalent to a radio running at full output power (1 watt +30 dBm) with a +6 dBi antenna. The antenna
cable must have sufficient loss to bring the EIRP below +36 dBm if a higher gain antenna is used. For
example, using a +8 dBi antenna with a radio transmitting at full power would result in an EIRP of +38
dBm. In this situation, the antenna cable must provide at least 2 dB loss in order to bring the EIRP into
compliance.
SpeedNet Radios have the ability to decrease transmit power. Any confirmed decrease in output power
should be considered when calculating EIRP.
