Edit: I'm looking for an antenna, not criticism on whether I need one, all the rest is just background😉
My family enjoys short day hikes through heavily wooded countryside with mild hills.(Northen Michigan.)
The problem is navigating. Cell signal is spotty at best so GPS is pretty much out of the equation and orienteering (using compass + map +line of sight) is out due to lack of line of sight.
Actually, navigation isn't a big deal, just stay on the trail and use a pedometer to track steps. I'm a gadgeter so I'll take any excuse to solder and learn something.
I know about as much as the average Joe about RF (pretty much nothing) but I got a few keywords. Looking for a highly directional antenna, preferably as small as possible though I know antennas are sized by signal.
I'm pretty sure AM/FM should be available out there (haven't taken a pocket radio out to check,) any other bands I should consider?
A loop antenna seems like it's best because it is flat but might not be directional enough. I apologize, I have more questions than answers and would greatly appreciate any help on the subject or keywords to google to death. Also this is my first time here so criticism [on the post] is encouraged.
