There are three types of GPS antennas available for the GPS-referenced products supplied by Masterclock®.
The "basic" package is designed for installations where a short antenna cable 16 ft (5 m) can be used. For installations where a longer antenna cable is required the "standard" package allows cable lengths up to 500 ft (150 m). Operationally, the antennas are equivalent. Both antennas are water/moisture resistant, with 26 dB and 32 dB amplification respectively and are suitable for indoor or outdoor mounting.
A 40 dB "high-gain" antenna is also available for congested cell-site applications or for applications requiring longer cable runs. Pipe-mounting hardware is included.
The difference between the three antennas is physical packaging, gain, mounting and the different lengths of antenna cable that can be used.
