Check mounting and connections for the antennas

Verify that both the GPS and transmitter antennas are mounted correctly, and securely attached to the correct connector on the TX325. The GPS antenna cable has an SMA connector that fastens to the GPS port of the TX325. The transmitter antenna connects to the RF Out port on the TX325.

Visually inspect both antenna cables looking for breaks, frayed wires, and corrosion on the connectors and ports.

Valid GPS antennas include the following. Refer to www.campbellsci.com/order/tx325 for more information.

• 27 dBi GPS Antenna with Magnetic Mount and cable: This antenna is for applications where signal strength is strong and the likelihood of snow is low.

  

• 28 dBi GPS Antenna, Jam Resistant:This antenna is better for all weather conditions and for applications where a weak GPS signal may be present. This antenna requires the purchase of an GPS antenna cable.

  

  NOTE:

  If using surge protection with the GPS antenna verify the surge protector is DC coupled so that it can supply power to the antenna. Campbell Scientific offers a suitable kit (www.campbellsci.com/order/tx325 ).

For the transmitter antenna, Campbell Scientific recommends using the GOES Yagi RHCP Antenna listed on the website (www.campbellsci.com/order/tx325 ).

Refer to Data collection platform (DCP) installation for instructions about correctly mounting the GPS and transmitter antennas.
