 		 #185159 - If already drawing cables to slaves then one antenna easy
Responding to: ???'s previous message
Having one GSM module - with subscription - for each slave would be expensive.

Drilling hole for wire from master to every slave would mean it would be quite simple to place the master where a GPS antenna cable can also be installed.

And it's easier to get enough signal to get time than it is to get enough signal to get a valid position.
