6. Secure the radio bracket onto the RTK vertical antenna
extension. Place it as high as possible, just underneath
the GNSS antenna, as shown. Placing the radio too low
will reduce the radio range.
7. Connect the external antenna cable to the GNSS antenna.
8. Connect the other end of the external antenna cable to the
ProMark3 RTK. Lift the flap on the side on the unit to
access the antenna input connector.
9. Connect the radio cable to the back of the receiver. The
connection is secure after you have fully tightened the
thumb screw.
10.Place the ProMark3 RTK receiver into the field bracket.
11.Attach the field bracket / ProMark3 RTK combination
onto the tripod.
12.Measure and record the instrument height (HI) of the
GNSS antenna:
• Slant measurement (preferred): Use the measurement
tape provided. Insert the end of the tape into one of
the three or four hooks located on the circumference
of the GNSS antenna radome. Unroll the tape toward
the reference point. Position the tip of the tape meas
-
urement onto the reference point. Block the tape and
read the value indicated at the base of the tape: this is
the slant height.
• Vertical measurement (more difficult; tribrach and tri-
pod are in the way): Use a conventional tape to meas-
ure the vertical distance from the base of the GNSS
antenna to the reference point.
13.Turn on the ProMark3 RTK and check that the green LED
indicator on the radio is on. This means the connection
between the radio and the ProMark3 RTK is correct and
the radio is normally powered.
The higher the radio, the
better the quality and
range of the radio link.
Warning!
Unscrewing the radio
antenna protection is
pointless or even hazard-
ous for the antenna.
