Orolia 8230AJ GPS/GNSS Antenna

The Orolia 8230AJ is a high gain (40 dB) GNSS outdoor antenna covering GPS L1, GLONASS L1, BeiDou B1, Galileo E1, and QZSS L1. Similar to our proven Model 8230, it uses a three-stage low noise amplifier, a mid-section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The active antenna circuitry uses +5VDC (provided by the Orolia timing receiver over the antenna coax).

Similar to the standard Model 8230, this antenna is also terminated with a type “N” female connector and mounts to standard pipes via its own unique L bracket. Making it a drop-in replacement for existing installations. Its weather-proof housing is IP67 compliant offering a high degree of protection against dust and water. Its cylindrical radome is made of high impact UV stabilized polycarbonate to protect against rain, ice, snow and salt spray.

Standard or AJ Antenna – Which Should I Use?

The standard antenna sees the entire view of sky, equally receiving signals from satellites at the horizon or the zenith and all points in between. However, there is increasing interference in the GNSS L1 band, whether unintentional from other transmitters like communications towers or intentional from illegal “privacy jammers”. The AJ antenna rejects signals for the lower elevation angles – where most of the interference comes from – and only receives signals from the higher elevation angles where the satellites are. Of course, this reduces the number of satellites the receiver will see, but for the timing application, only a few satellites are needed. Moreover, with multi-constellation receivers, there are an increasing number of satellites available. So you get all the performance in timing accuracy you would get with a standard antenna plus 20 dB or more of interference rejection.

Antenna Cable & Accessories

Orolia recommends low loss coaxial cable such as Times Microwave LMR-400 for the antenna cable. The attenuation characteristics of the LMR-400, or equivalent, at the GPS L1 frequency (1575.42 MHz), along with the high gain of the antenna allows the cable length to a maximum of about 125 meters (400 feet). Orolia offers standard and plenum rated cable assemblies. For installations where the antenna cable length exceeds 125 meters Orolia offers a variety of accessories to extend cable lengths including inline pre-amplifiers (Model 8227), fiber optic links and frequency down-up converters. The receiver powers the GPS antenna and most accessories. Orolia recommends installing a lightning protection device in the antenna line to protect the receiver and connected devices. Orolia offers a Surge Protector, Model 8226, to shunt potentially damaging voltages on the antenna coax to ground.
