GPS 4-Ex

ATEX Certified GPS, Galileo, Glonass and BeiDou antenna for Mast Mounting in Hazardous areas

  • Passive quadrifilar helix antenna for fixed installation.
  • Covering GPS, Galileo, Glonass and BeiDou.
  • The antenna is specified as ATEX antenna for use in zone 2 in potentially explosive areas.
  • The antenna is to be used as a receiver only.

DESCRIPTION

  • Before installing the antenna, read the ATEX Product Manual carefully.
  • The antenna is suitable for use in gas groups IIA, IIB and IIC in zone 2.
  • Right-hand circularly polarized antenna (RHCP).
  • The circularly polarized antenna minimizes the fading effect often encountered in environments with reflecting obstacles.
  • Mounting bracket available to make the perfect installation for your specific needs.
  • All metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
  • Maximum recommended cable loss between antenna and receiver is 9 dB (e.g. 20 m RG 58 A/U-XLL) for receivers with acquisition sensitivity of < - 142 dBm. Higher cable loss can be tolerated for receivers with lower acquisition sensitivity.
