1 Introduction
The AT1621-20 antenna is designed for Iridium applications where long RF
cables are needed and a passive antenna cannot be used. The AT1621-20 has
an integrated power amplifier (for transmitting signals to the satellite) and
low noise amplifier (for receiving signals from the satellite)
2 Important Safety Information Regarding Exposure to RF
Signals
WARNING
To satisfy FCC RF exposure requirements for mobile
transmitting devices, the minimum safety distance is
55 cm (21.7 inches). This separation distance should
be maintained between antenna and people during
operation of the antenna.
3 Cable Length Requirements
To meet Iridium performance requirements and comply with FCC regulations,
care must be taken to use the appropriate total RF cable length. Your antenna
distributor should provide the appropriate cable.
Total Cable Loss
Requirement 13.3 dB total for two cables
Reference Cable
Set
5 ft (1.5 m) RG58LL 1.1 dB loss @1621 MHz
115 ft (35 m) LMR240 12.2 dB loss @ 1621 MHz
