- 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)
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.
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.
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.
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.
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).
