Hi Guys  :wave:

A pair of 'Schottky Diodes', 1 in each D.C. power-line to the Receiver Board, would provide good reverse-polarity protection.

'Schottky Diodes' drop an absolute minimum of Volts, compared to regular silicon types.

You can check the Voltage drop of various Ampage types, in your favorite suppliers catalogue data.

'Typically' the average Schottky Diode only drops around 0.25 Volts, sometimes less.

For a few Pennies each, It could be worth considering, to protect those expensive receivers.
