Any suggestions for how to get a signal through jungle canopy? Is a bigger/stronger antennae going to do anything or do i need to look into other devices?
Jungle canopy is very problematic in that the density is just so thick. What i do in heavily forested situations for satcoms is to get a good bearing and elevation with a compass and clinometer to the satellite location. Then move around to find that one spot where the light peers through, and setup there. It works very well for geostationary satellites..
You can use something like this http://www.giangrandi.ch/electronics/satcalc/satcalc.shtml to get the bearing and elevation (in advance if you know where youll be if no internet)
higher gain antenna will help you a lot, the problem in L-Band quite problematic to make a practical size and higher gain antenna then the Outernat patch.
Perhaps some carefully built helicals can give somewhat higher gain.
A reflector might be your best bet. If it's heavy foliage with no sunlight peering through, you might be taking a 10dB hit right off the bat.
