Some people use a directional yagi antenna on the canopy and a omnidirectional one behind the main gear. This combination seems to work very well with otherwise problematic carbon fuselages.

How is the secondary antenna placed? The one I received is flat but is supposed to be in a vertical attitude. I can't find a place that works in my mostly carbon Ventus. I think the blind spot issue is significant. My main dipole is mounted on the glare shield and I get good performance when the line of sight doesn't go through the carbon fuselage. It is easily noticed while thermalling when an alert disappears and reappears depending on the obstruction.
