Hi
Has anyone experimented with different antenna orientation placement on the P2V?
I was reading these tips on avoiding Flyaway here:
http://www.dronevideofx.com/?p=724
And the author suggested place the 2 antenna on the quadcopter (P2V) 90 degree to each other. So essentially one antenna vertically down like the way it is alone the landing skid, and one horizontally alone the body of the quadcopter/P2V.
As I understand it from another thread on antenna, the transmission is actually weakest alone the axis of the antenna as the signal is transmitted alone the length of the antenna in a magnetic field like pattern. The top and bottom of the antenna axis would essentially be a null area.
So in theory, placing the two antenna on the P2V 90 degree to each other would ensure maximum coverage from any angle. Especially when the tip of the RC controller antenna is directly line up with the tip of the antenna on P2V (weakest signal connection).
Any thoughts?
