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 technology. 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 GPR-
market 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.
