GPS Antennas Overview

Orolia online store

A selection of accessories are available in the Orolia Online Store (shipping to US addresses only).


Our systems approach offers standard GPS/GNSS antennas and related accessories for its precision timing products with embedded GPS/GNSS receivers.

A typical installation uses an outdoor antenna installation to collect and reliably transmit the RF of the collected signals to the embedded receiver (such as Spectracom's GPS NTP Servers). As a solutions provider, Spectracom offers best-in-class GPS antennas and accessories from 3rd parties into fully qualified and warranted systems. If you have a specific need for your application, we can assist with sourcing and procurement.

The recommended installation includes:
  • Outdoor GPS/GNSS antenna (model 8230)
  • Surge suppressor for lightning protection (model 8226)
  • Low-loss LMR-400 equivalent RF cable to connect the antenna to the surge suppressor and the surge suppressor to the GPS/GNSS receiver (type N)
Also available:
  • Mounting accessories for a roof-top antenna installation
  • Indoor GPS/GNSS reception options when an outdoor installation is not practical
  • Options for long antenna-to-receiver cable runs (> 400 ft, 125 meters)

Recommended Installation

GPS/GNSS Antenna

GPS/GNSS Outdoor Antenna

The Model 8230 is a high gain (40 dB) GNSS outdoor antenna covering GPS L1, Galileo E1, GLONASS L1, and BeiDou B1 . 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. ​

Key Specifications

Surge Suppressor

Model 8226 protects the receiver, and other inside equipment, from damaging voltages. Voltages exceeding the impulse suppressor trip point are shunted to the system ground. The surge suppressor is supplied with a mounting bracket. A Grounding Kit is also available.

Low-loss GPS RF Cable

Spectracom offers LMR-400 equivalent cable assemblies terminated with type N connectors. Order CA01-0N0N-3xxx, where xxx = length in feet. Contact us for special requirement cable.

Antenna mounting accessories

Spectracom offers various mechanical assemblies to support a reliable outdoor antenna installation.

SAASM Secure GPS Antenna

Anti-Jam Antenna

The Model 8230AJ is a high gain (40 dB) GNSS outdoor antenna. 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 Anti-Jam antenna rejects signals for the lower elevation angles – where most of the interference comes from.


SAASM GPS Outdoor Antenna

The Model 8225S is a GPS outdoor antenna covering GPS L1 and L2. It is compatible with all other acccessories for the recommended RF cable installation including the model 8226 surge suppressor and CAL7 RF cable. ​

Options for Long Cable Runs

Inline Amplifier

Model 8227 is a convenient solution when the GPS RF falls below the receiver's recommend minimum input. While the maximum cable length depends on thegain of the antenna, loss of the cable and sensitivity of the receiver, we find that the inline amplifier can extend a cable run by 400 feet.

RF Down-Up Converter Kit

Another approach to long cable runs down converts the GPS RF frequency in a specialized roof-top antenna to minimize signal loss and allows RG-58 cable to extend up to 1,500 ft (450 meters). The kit comes with an upconverter that is installed near the GPS receiver.

Fiber Optic Link Kit

A fiber optic link can bridge a long antenna-receiver distance and provides for electrical isolation. A typical kit can link a fiber transmitter and receiver is via 9/125 micron singlemode simplex fiber (SC/APC connectors) up to 5 miles (8 km).

Technical Notes and Briefs

More Info
Facilities with connections to the outside may suffer damage due to lightning. Electronic components are extremely sensitive to high voltage from major energy sources such as lightning, which is the most common danger. It also has the characteristic of being completely unforeseeable. To protect people and equipment from lightning, it is essential to ensure that all wired connections from building exteriors include the appropriate form of protection.

More Info
Many Orolia timing and synchronization products utilize an embedded GNSS (Global Navigation Satellite Systems) receiver as a primary reference. Typical installations utilize an outdoor active GNSS antenna to collect and transmit GNSS satellite radio signals to the receiver via an RF cable. This technical note describes the main considerations for a successful outdoor GNSS antenna installation for a timing application:
