Installing Topcon Hiper-AG RTK Fixed Base Station
Self-Amalgamating Tape
Self-amalgamating tape is supplied. Using the tape to seal all external
antenna connections is recommended. The use of this tape will reduce
the chance of water ingress with consequent transmission failures.
UHF Collinear Antenna Cable – RG213
The UHF Collinear Antenna cable is a low-loss cable which should
be treated with care; sharp bends, nicks and cuts to the casing must be
avoided.
The supplied Antenna cable is 50’ (15m) in length. There is a 60’ (18m)
cable available at an extra cost, if required for taller towers etc.
The cable has an N-type connector at each end.
One N-type connector is connected to the Lightning Arrestor near the
UHF Collinear Antenna (Figure 6-6 on page 6-7) and the other end is
connected onto the Hiper-AG unit (Figure 6-3, page 6-3).
Any damage to this cable could cause severe reduction in the radio
transmission strength.
Once the UHF Collinear Antenna cable is securely
fitted to the Lightning Arrestor, firmly wrap the
connections with the self-amalgamating tape.
This will stop any moisture infiltrating the connections
and causing signal loss.
