ACTIVE SATELLITE ANTENNA SYSTEM FOR THE IC-SAT100

AH-41

Active Satellite Antenna System for Using the IC-SAT100 Satellite PTT Radio in a Building

Descriptions

・Covers both Iridium® satellite frequencies and GNSS L1 band frequencies, and provides a solution for satellite communications indoors

・Use optional OPC-2462 (59 m, 193.5 ft) or user supplied coaxial cable (Max. 169 m, 554.5 ft) to obtain a line-of-sight path to the satellite

・Power over Coaxial (PoC) carries electrical power through the coaxial cable
– Electrical power cabling can be reduced

・Separate TX/RX unit configuration, TX unit with a Power Amplifier and RX unit with a LNA (Low Noise Amplifier)

・The main unit has IP67 waterproof and dust-tight protection for outdoor installation

Connection example

Types of External Antennas for IC-SAT100 and Usage Guidelines

By replacing the IC-SAT100 antenna with an external antenna, satellite communication is possible even from a vehicle or building. Select the most suitable antenna according to the installation location and application.

1 OPC-2422 coaxial cable (5 m, 16.4 ft) is required for more than 1.5 m, 4.9 ft extension.

2 Optional OPC-2113 or user supplied coaxial cable is separately required. Cable loss requirement is less than 3.4 dB loss at 1621 MHz.

3 Optional OPC-2462 or user supplied coaxial cable is separately required. Cable loss requirement is 12.5 - 13.0 dB loss at 1621 MHz. 

4 The distance from the main unit to the antenna is a rough guideline. The height of the building is an estimate assuming that the height of one floor is 3.5 m, 11.5 ft .
