Hey everyone. I'm thinking about maybe replacing my stock transmitter 5.8 antenna with something with a little more gain. I don't want to get into boosters or anything. Does anybody know the gain (in db) of the stock antenna? I have successfully flown out to 1800' out at 370' high. This was my best distance. I often have weak signal issues with the 5.8 at around 500' depending on antenna position and the quads orientation. 2.4 has never dropped or become weak. Thoughts?
