Introduction
Set Up the RTK Rover
At this point, you should have pretty much everything
prepared and all that’s left for you to do is get the rover
connected to the monopod, turn it on and confirm your
communications between the rover and the base.
This is also where the benefits of having an external UHF
antenna attached to the TRIUMPH-LS can be seen allowing
your signal gain to increase without worry in exceeding
your licensed maximum effective radiating power, typically
35 watts ERP.
Having previously attached the TRIUMPH-LS’s external
antenna to the UHF port located on the left side (as viewed
facing the screen display), proceed to configure the external
antenna. Otherwise, the TRIUMPH-LS’s internal UHF
antenna will ably perform in receiving corrections.
From the Home screen, tap on the UHF icon to bring up the
Radio Status screen. Look for your received signal strength
indicator (RSSI) value. It is a measurement of the power
present in a received radio signal. These values take several
seconds to be populated in the table, so be patient. You
should also see your Received, Lost values being updated.
To switch configuration between Internal and External UHF
antennas, from the Radio Status screen tap on Configuration ,
tap chosen antenna, then tap OK; alternatively, press the +
key.
The re-initiated radio communications will be seen in the
UHF Radio Status screen; i.e., their respective RSSI and
Received, Loss values, and as noted earlier will take several
seconds to be populated in the table, so be patient.
Most generally, you will benefit from increased Radio
Signal Strength Indications whenever the external UHF
antenna has been attached and configured; however, there
may be certain environmental circumstances where there
can be little or no increase as shown in the examples on
the right. Before deciding upon the day’s UHF frequency
for broadcasting corrections, or later if you find reason to
suspect performance degradations, bring up the Radio
Status screen and tap on Interference. Here you will be able
