The Pi up the mast at the antenna was an idea that worked fairly well <br>
except for the dongle "disconnect", and intermittent RFI on 145.825 from <br>
the Cat5 cable to the Pi. The installation was for ADS-B (1090MHz). My <br>
masthead box now contains a LNA4ALL and 1090MHz BPF, and the Pi hangs on <br>
the wall in the shed, which I find much more convenient. Current uptime <br>
on that Pi is 99 days. Maybe you'll have similar success.<br>
