Product overview

The HDR-series (High Dynamic Range) is the latest addition to MALA’s versatile
product range. It is, from bottom up, a complete new design, based on patented
cutting edge technolog y. These new antennas are hence not just an upgrade of
earlier designs; they represent a leap in GPR-technology, not seen in the past 15
years. Due to the internal design, the HDR-antennas are self-contained GPR
systems, so, naming them antennas is somewhat misplaced. Each one of them
actually contains a full-blown GPR system

Compared with earlier, comparable systems, this new suit of GPR-systems is
capable of much faster data acquisition rates, without violation of the FCC, EC and IC
regulatory limits on emissions. Combined with increased bandwidth, this extreme
performance gives the user a system with unprecedented dynamic range and
resolution.

At the end of the day, these products give the GPR community access to easy-to use
systems with significant deeper penetration as well as better detection capabilities.
Add to this the positioning options, software capabilities and proven accessories and
you have in your hands full access to the GPR-future. Never before has the GPR­market been offered so much value for the money.

Scope

This manual describes the MALA HDR series of shielded antenna. It’s a hardware
manual, intended to give users a fast guide for handling the antenna units in the field.
It’s not a complete system manual. For further information on using the GPR system,
please refer to the software manual for the monitor you have bought with the system.

1.1 Unpacking and Inspection

Great care should be taken when unpacking the equipment. Be sure to verify the
contents shown on the packing list and inspect the equipment for any loose parts or
other damage. All packing material should be preserved in the event that any
damage occurred during shipping. Any claims for shipping damage should be filed to
the carrier. Any claims for missing equipment or parts should be filed with MALA
GeoScience.

1.2 Repacking and Shipping

If original packing materials are unavailable, the equipment should be packed with at
least 80 mm of absorbing material. Do not use shredded fibers, paper wood, or wool,
as these materials tend to get compacted during shipment and permit the instruments
to move around inside the packag e.

1.3 Safety and Compliance, user notices

This GPR -device is certified according to FCC, subpart 15, IC RSS-220 and ETSI EN
302 066-1&2.

If this device is opened, or in any way tampered with internally, all warranti es ar e
void. Furthermore, if any changes or modifications are done internally, the users
authority to operate the device may be void, in accordance with FCC §15.21.

According to the regulations stated in ETSI EN 302 066-1 (European
Telecommunication Standards Institute):

The control unit should not be left ON when leaving the system unintended. It should
always be turned OFF when not in use.

The antennas should point towards the ground, walls etc. during measurement and
not towards the air.

The antennas should be kept in close proximity to the media under investigation.

Canadian and US regulations states that whenever GPR-antennas are in
use the following notes apply:

This Ground penetrating Radar device shall be operated only when in contact with or
within 1 m of the ground.

This Ground Penetrating Radar Device shall be used only by law enforcement
agencies, scientific research institutes, commercial mining companies, construction
companies and emergency rescue or firefighting organizations.

This device complies with Industry Canada license-exempt RSS standards.
Operation is subject to the following two conditions: (1) This device may not cause
interference and (2) this device must accept any interference, including interference
that may cause undesired operation of the device.

French translations:

Cet instrument de Géoradar se devra d’être opéré seulement en contact à même le
sol ou en deça d’un mètre du sol.

Cet instrument de Géoradar se devra d’être utilisé seulement par les agences
chargées de l’application de la loi, les instituts de recherches scientifiques, les
