Hello Steve: One possible solution is a Elecraft XG-3 (at 0 dBm) as a start - with a 13 dB amplifier (pretty simple). https://static.dxengineering.com/global/images/instructions/ect-xg3.pdf
Greg, W8WWV used a XG-3 for elevation pattern measurements using a drone and presented his findings at Hamvention 2015 - The Antenna Forum.

These oscillators will give me about 20 mW max, but I need a bit more since I plan to mount it on my small drone and will need a bit more range. My drone can lift up 130 grams, so I’d like it to run on a 5v supply. (maybe a 9v battery with regulator or 3 AAA cells) I considered something like a Mini Circuits PHA-13ln 21 dB monolithic amp, but not sure thats such a good idea. A 2N5109 base amp is a current pig and too heavy. Any ideas? 73, de steve ve6wz _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
