I tried to make a decent comparison between a V antenna paired to a 9dbi Yagi and a Skew planar antenna paired to 6 turn Helical.
The linear was tested on a cloudy day with no wind and the CP was tested on a nice sunny day but it was windy and I was getting dealt to when I dropped down to tree level over the river. The most notable thing is flying up under the power lines (110kv)
I had the SPW on the wingtip of a 2 meter foam glider which was not ideal because of the drag but I wanted to see if it was worth a permanent change. i am going to make a new 6 turn Helical and see if I can get better performance.
In my opinion at 1010mhz the jury is still out on whether the extra drag is worth it.

Let me know what you think guys and I was wondering if anyone else has compared linear to CP at lower video frequencies, I am almost certain 2.4ghz and above it is almost compulsory depending on where you fly.
