Antenna Configuration / Position Antenna / Vector Antenna
Use these settings to define the antenna being used by the receiver.
Select Receiver Configuration / Antenna.
Antenna Type – Select the type of antenna being used with the receiver.
RINEX Name – Allows the selection of the type of antenna being used with the receiver using the RINEX name of the antenna rather than the Trimble name for the antenna. Setting this field automatically sets the antenna type in the preceding field.
Antenna Serial Number – Enter the serial number of the antenna being used.
Radome Serial Number – Enter the serial number of the radome enclosure.
Antenna Measurement Method – Select how the antenna height is being measured.
Antenna Height [m] – Enter the measured height of the antenna. This is typically measured from a ground marker or the mounting point of the antenna.
Gain Amplification – Enable Gain Amplification if the sum of the antenna gain and the total cable loss is less than 38 dB. For example, if the antenna gain is 30 dB and the cable loss is 8 dB, then the sum is 30-8=22 dB (cable loss is negative) of gain. In this case, enable the Gain Amplification. Trimble antennas have an antenna gain of 50 dB and a maximum suggested cable loss of 12 dB for a total of 38 dB system gain, so the Gain Amplification should be set to Disabled. If a Trimble antenna is used with a very long cable run that has, for example, a 20 dB loss, then the system gain is only 30 dB, so Gain Amplification should be Enabled.
Apply Antenna Correction to – When the RTCM V3 check box is selected, the Base antenna is set to a “Null Antenna” and no antenna model parameters are sent to the rover receiver. When using Trimble receivers exclusively, Trimble recommends that you select the check box. In some case, when using a third-party rover receiver, the check box should be left cleared and the antenna model parameters are sent to the rover. To determine the settings for this parameter, check with the third-party manufacturer.
TIP – If available, an image of the selected antenna is displayed so that you can confirm that you have selected the correct antenna.
