Figure 3: L1 GPS Antenna - methods for cabling and mounting
GPS Signal Strength Requirements
Refer to Figure 4:The required gain at the GPS receiver’s ANTENNA connector is greater than 20 dB
and less than 36 dB. A 150 foot length of RG-59 coax cable of has a loss of 16-21 dB, which meets this
requirement. Abide by the minimum input gain requirements if using other cable types. Additionally, if
changing the antenna, abide by the 41 dB gain requirement. Other factors, such as radiation, coverage,
