" What does a reverse polarity protection circuit look like ? "
A reverse polarity protection circuit is a simple & cheap solution for receiver protection.
It looks like this ...
A 'Schottky Diode' is always the best option here ...
... due to it's very low 'forward Voltage drop'.
A 2nd 'Schottky Diode' could also be added to the negative power-line ...
... the other way around, with it's 'arrow' pointing towards the battery 'minus' terminal.
No matter how much testing of batteries one does, or how 'reliable' the supplier is ...
... MISTAKES HAPPEN ! ... & '20-20 hindsight is a wonderful thing' as they say.
The 'Schottky Diode' circuit costing a few Pennies & a few minutes to install ...
... could save you FIFTY $$$ BUCKS !!
