I've done some searching, but I'm not finding quite this topic....
What I want to do is have a pocket sized wireless transceiver with Arduino programmability, running on 2 or 3 AA's - a moteino would be perfect, except that I'm not sure how to handle the antenna.
My "default" solution would be an Arduino Pro Micro 3.3v + nRF24L01+, but I'd like the range of 433 MHz, and the compactness of the Moteino. But I'm not sure about how to fit the antenna into a small package - which should certainly be smaller than a cigarette pack.
For a wireless sensor node a monopole wire antenna hanging out would often be no problem but in a pocket it would be. Would I need to reserve a space inside the case for a coil similar in size to another AA battery? Or what?
Moving to 915 MHz would cut the length/size of the antenna, at some cost of range, right?
Thanks for any experience or ideas.
