This is a resend. My apologies if it shows up twice.

With the help of some Velcro, I mounted my Outernet patch antenna to a
flat, smooth, 10 x 12 inch aluminum cooking sheet and set 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.
