Optimising the Antenna for Rx Signal
When using a directional antenna, it will be necessary to align the antenna for the best received
signal. This can be done using TVIEW+ Diagnostics or by measuring the RSSI output on Pin 9 of
the serial data port. RSSI voltage of 2.5v is approx. -90dBm. Slope is equal to 20dB/volt.
