Model 62000 Palm Antenna
Thank you for purchasing the Model 62000, 2000 MHz Palm Antenna. The Palm Antenna
combines exceptionally fine resolution in a small package. Its small size will help the concrete
scanning professional to get into areas which are too tight for conventional antennas.
The Palm antenna incorporates an integrated survey wheel which can change position and allow
you to use the antenna in a cross-polarized configuration to aid in the detection of non-metallic
objects. The Palm antenna also comes with an integrated control cable with a length of 7 m
(22.75 feet). There is also an antenna safety attachment point 1.5 m (5 feet) from the antenna. If
you are working high above the ground, GSSI recommends attaching the safety point to your belt
so that the antenna will not be damaged if you drop it.
The Palm antenna is backward compatible with previous GSSI SIR Systems.
Note: The indented vertical lines on the sides of the antenna housing denote the center of the
antenna. When marking locations on the concrete, this is the reference point on the antenna to
mark.

“Deadman” Switch Operation (IMPORTANT!)
In order to comply with various emissions standards imposed by various governments, the Palm
antenna incorporates a “Deadman” switch which will turn off the transmitter when the operator
is not using the antenna. The Palm antenna incorporates two “Deadman” devices: the blue button
on the top of the antenna housing and the survey wheel. When neither of these is used, the
antenna will shut off after 10 seconds. It will resume instantly if the survey wheel is moved or
the button is pressed.
