  • GPS antenna alternatives

    This is what my shadow map looks like after 18 hours. As expected, there's not much low-elevation stuff in some directions because of trees. In other directions, where the optical horizon is 20+ km away, satellites are being received at elevations as low as 3°. The 'polar hole' is clearly visible.

  • GPS antenna alternatives

    Just to add to this dormant thread, yesterday I installed a PCTEL GPS-TMG-40N antenna with low-loss feeder and it certainly does the trick. I went for the 40 dB version so there's plenty of signal in hand to feed a 4-way passive splitter when I get one. I'm somewhat screened by tall trees in the south-west quadrant, so don't get many low-elevation signals from there.

    The KiwiSDR GPS software only seems to allow a maximum of four Galileo satellites in the 12 channels. Is this intentional? While it all works fine, it would be nice if the limit could be raised - either by allowing more than four Galileo sats, or by allowing more than 12 channels. Also, surely there isn't much point in scanning for QRZZ satellites in Region 1?
