ANTENNAS

 

A comprehensive line of non-contacting and contacting, GPR antennas are available for near-range bridge and pavement evaluation, utility location and geotechnical applications requiring depth capabilities up to 4 meters and for location of reinforcement, electrical conduits and concrete inspection. All of Penetradar's GPR antennas are IRIS/IRIS-P compatible. Contact us for additional information and specifications.

 

 

NON-CONTACTING ANTENNAS

The Model 30AGC and 60AGC antennas are lightweight and compact, high performance TEM mode horn antenna/transceiver combinations designed for non-contacting GPR operation. These antennas exhibit ultra wide band performance and very low VSWR, with minimal distortion throughout the bandwidth of the applied signal. Its high directivity beam minimizes interfering clutter sources. These antennas are optimized for applied signals within the range the range of 0.5 ns to 2.0 ns and are available in both mono-static and bi-static configurations. Transceiver units are interchangeable depending on desired pulse width. Penetradar non-contacting antennas are constructed of low dielectric material with a hard plastic outer covering for durability and high speed (60MPH/100km/hr) operation. When ordering specify antenna and transceiver pulse width.

GROUND CONTACTING ANTENNAS

The 2 nanosecond (500MHz) Model 501B, 2.5 nanosecond (400MHz) Model 401B and 3 nanosecond (300MHz) Model 301B are mid-frequency and low frequency contacting-type ground penetrating radar antennas with penetration depths of approximately 6 feet (2 meters), 9 feet (3 meters), and 12 feet (4 meters), respectively. These antennas are optimized for ground contacting operation and can be pulled manually or towed by a vehicle. The Model 401B/501B can also be suspended from a vehicle in close proximity to the ground and when properly installed can be operated at speeds up to 35MPH (55km/hr). These antennas are a shielded, broadband dipole design that optimize bandwidth and minimize distortion resulting in superior subsurface detection capability. Uses for these antennas include detection of subsurface pipes and utilities, measurement of thick pavement layers, geotechnical applications including detection of underground storage tanks (UST’s) and for a wide variety of general site inspection applications. The 501B/401B/301B antennas are housed in a rugged plastic enclosure for high durability and incorporate removable wheels for maximum mobility. These antennas are compatible with all Penetradar GPR systems and software.

HAND-HELD ANTENNAS

The Model 1001B, Model 2001B and Model 2501B are shielded, handheld contacting type antennas used for near range (shallow depth) inspections. These antennas emit 1ns (1GHz) and 0.75ns (2001B) and 0.5ns (2501B) monocycle pulses at high PRF. This family of antennas are optimized for near range and high resolution with maximum depth range of 1m (1001B), 60cm (2001B) and 45cm (2501B). The 1001B/2001B/ 2501B antennas are housed in a light weight aluminum enclosure. Typical applications include rebar location & mapping, rebar depth measurement, electrical conduit location, void detection and thickness measurement. For remote inspection an optional telescoping handle is available, and for subsurface “imaging” Penetradar’s FocusCell software is available.
