Does anyone have an accurate estimate of how deeply, if at all a
common childs remote controlled toy cars transmission can penetrate
seawater to control the car? A difficult question I admit!
Are there any RF frequencies that are better at penetrating seawater
than others and if so what are they?
The application is for a 15m max, close range transmitter of some sort
(RF, IR?) to remotely instruct an under water (up to 7meters deep -
tidal) device to activate a solenoid or motor. Most probably it's be a
motor or servo of some sort as solenoids are so expensive and using a
cheap toys components would be an advantage for costs sake.
