I mounted the patch antenna on the front of a plastic board with the amplifier, receiver, and
raspberry pi 3 on the other side. I am powering it with the Raspberry pi wall power supply. The
first few days I had a reasonable signal of around 3 db and signal state of 3 to 4. I was receiving
ok with the weather data, wiki posts, aprs, pics and stuff like that.
My signal had gone down to around 2 db with a signal state of about 3. I have tried re positioning
the antenna but am stuck around these values. I am setup inside the apartment house looking out
the window and have taken the setup outside with about the same results.
I also notice quite a bit of interference from the computer and monitor since the setup is about 4
feet from the system. So I keep the computer off when taking the readings and positioning the ant.
