GPSANT:
GPS Antenna/Converter Unit

The GPS antenna combines a planar antenna and a frequency converter, which translates the high-frequency phase-modulated spread spectrum signal of the GPS system to an intermediate frequencyo al cielo abierto

Key Features:

  • antenna connected with up to 300m of standard coaxial cable RG58
  • holder for wall mounting
  • preformed cable
  • clamps for pole mounting
  • Ambient Temperature: -40°C ... +65°C

The antenna/converter unit can be mounted on a pole with a diameter up to 60 mm or at a wall. A 50cm plastic tube, two holders for wall-mounting and clamps for polemounting are added to every GPS167. A standard coaxial cable with 50 ohms impedance should be used to connect the antenna/converter unit to the receiver.

The maximum lenght of cable between antenna and receiver depends on the attenuation factor of the used coaxial cable.

Example:

Type of cable diameter Ø [mm] Attenuation at 100MHz [dB]/100m max. lenght [m]
RG58/CU 5mm 15.9 300 1
RG213 10.5mm 6.9 700 1
1) This specifications are made for antenna/converter units produced after January, 2005

The values are typically ones; the exact ones are to find out from the data sheet of the used cable.a
