With the help of some Velcro, I attached my Outernet patch antenna
to a flat, smooth, 10 x 12 inch aluminum cooking sheet and mounted it
indoors on a tablet stand. I angled the antenna at 50 deg. above the
horizon and pointed the stand in the direction of the satellite. Antenna
pigtail is at the bottom. LNA is connected directly to the pigtail and
Outernet SDR is connected directly to the LNA. I used a 9 inch USB cable
to connect the dongle to my Raspberry Pi 3. With this setup I was able
to increase my SNR from a max. of 1.7dB to > 5dB. A very easy setup that
now makes it possible for me to download Outernet files.
