4.1.3. External Antenna Setup
The TRIUMPH-1 receiver can also be used with an external antenna. Follow the steps below to
connect an external antenna to TRIUMPH-1 and measure its offset.
1. Attach the antenna to a tripod or bipod and center it over the point at which data will be
collected.
2. Measure the antenna height, as described in “Measure Antenna Height” on page 72.
3. Record the antenna height, point name, and start time in the field notes.
4. Attach the flexible RF cable from the external antenna to the antenna connector on the
bottom panel of the receiver.
The TRIUMPH-1 antenna default is set to
Auto
, allowing the receiver to detect automatically the
available antenna (whether internal or external). If you have changed this setting, or the receiver does
not detect the external antenna, use the procedure described on page 59 to set the External Antenna
detection option.
