GPS/GNSS Antennas and Accessories

GPS/GNSS antenna
Model 8230: GPS/GNSS L1 antenna

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. 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 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 surege suppressor to the GPS receiver (type N)
Also available:
  • Mounting accessories for a roof-top antenna installation
  • Indoor GPS 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 and GLONASS L1. 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 CAL-7xxx, 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


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. ​

Key Specifications

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).

Options for Indoor GPS

Skylight Indoor GPS Timing System

Consisting of an indoor GPS antenna panel, a configuration of Spectracom’s SecureSync® modular GPS time server, and an interconnect cable, Skylight opens new possibilities for accurate GPS time.

  • An option for leased facilities, urban canyons, buildings with prohibitively expensive cable runs
  • Attractive antenna panel designed for office installations
  • Works with other Global Navigation Satellite Systems for improved reliability
  • High stability internal oscillator maintains precise time even when GPS signal is intermittent
