Attaching an External
Radio Antenna
When purchased with an internal UHF or FH915
radio, the TRIUMPH-LS comes with an external
reception of your base station's corrections by the rover
can be enhanced using an external UHF antenna. Begin by
attaching the external antenna. In this image, we see the
2.5 dB gain antenna attached to the TRIUMPH-LS.
For the purposes of this discussion it is assumed that you
have already attached the external UHF antenna, are in
the field, the LS is powered on, that it's setup as the RTK
rover, the RTK base is on and the UHF radio is broadcasting
corrections.
Even when the external UHF antenna is attached, the default
internal UHF antenna will be used until you configure the LS
to behave otherwise. From the Home screen tap on the UHF
icon to bring up the UHF status screen. Notice the Received
Signal Strength Indicator's (RSSI) value before proceeding
to tap Configuration, select External Antenna and tap OK.
Anytime the UHF communications are interrupted; such as
in this example, it will take a few seconds up to a minute or
so for them to be reestablished.
