10.1 Antenna handles
The wooden antenna handles (see Fig. 4.1) are used for
carrying the unshielded antennas and stabilizing the antennas
during measurements (when not using a skid box).
The handles are mounted together using the set of 8 screws
and nuts. Mounting both horizontal bars for maximum stability
is strongly recommended. The bars come in 0.6, 1.0 and 2.0
meters lengths for use with the 200, 100, 50 MHz antennas
respectively. These are only recommended antenna
separations. The operator is however free to select other
transmitter/receiver offsets as desired.
The handles attach to the antenna electronics using the metal
locks on each side. It may be necessary to adjust the metal
hooks on the electronics for firm attachment. The handle tops
are intended for use when the antennas are moved individually
without the horizontal bars. This is the case when performing
e.g. CMP or WARR type of surveys.
NOTE: If antenna separations other than the standard ones
mentioned are used it will be necessary to edit the header file
for correct depth scales to be displayed by the software.
Wooden separators or the 25 MHz antennas are not practical
because the recommended antenna separation for this
frequency is 4 meters. MALÅ GeoScience provides 4 m long
strapping for this purpose.
