Component Signal Level Manufacturer Part Number Notes

GPS Received Signal -110 to -149 dBm (-130dBm typ)
Repeater Regulated Output -79 dBm GLI-METRO Auto Regulated at -84dBm
Cable Loss -5 dB Line Loss from Repeater to Tx Antenna

GPS Transmit Power -84 dBm L1-Band XMT Antenna RF Input Power
Repeater Antenna Gain 3 dB Antcom 3G15
Ptmax -81 dBm

Path Loss @ 43m -69.1 dB Path Loss = 20 Log F (MHz) + 20 Log d (m) - 27.55

EIRP @ 43m from Bldg -150.1 dBm/24 MHz 1575.42 MHz Frequency L1
30 m Outside Bldg
13 m Antenna to Bldg Walls
43 m Total Distance

PR (EIRP) = Ptmax - 20log f -20log (30 +d) +27.55 = -81- 63.95 - 32.67 + 27.55 = -150.1 dBm/24 MHz
