The HD7 Series antennas are circularly polarized, US models are RHCP (Right Hand Circularly Polarized) and European models are LHCP (Left hand Circularly Polarized). Because of the circular polarization, the orientation of the RFID tag antenna will not affect the performance of readers. With 7 dBic gain, these antennas provide significant performance improvements over a micro-sized patch.

They can be mounted in any setting, including directly against metal, and can be used indoors or outdoors. Please note that the integral N Female connector is mounted on the back of the antenna.

The HD7 antennas are compact and aesthetically pleasing, measuring only 8.25” H x 8.25” W x .75” D (21 cm x 21 cm x 1.9 cm). Not only is the radome attractive, but it is also the toughest RFID antenna that we have designed and produced to date. The antennas are provided with 4 corner holes with metal reinforcing bushings for mounting flush to a surface. This mounting style provides the most versatile mounting options for this product while maintaining the impact ability. The HD7 Series has a DC shorted front end and is compatible with antenna sensing circuits found in the current generation of RFID readers.
