Hi Mal,
NAVSTAR could be:
The satellites transmit on two L-band frequencies: L1 = 1575.42 MHz and L2 =
1227.6 MHz. Three pseudo-random noise (PRN) ranging codes are in use.

Hi All
I have a ships small LF antenna NAVSTAR. It is enclosed in a white plastic
case and the actual antenna is a single sided copper clad board 475 mm
long
by 35 mm wide. This is attached to an amplifier with 3 transistors, one
2N3823 and two 2N3904, there are two pot cores at the output side going to
the coax to RX.
Does anyone know this antenna/amp or have a cct and voltage info.
