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.

The planes I have seen with dual antennas have the yagi from Dolba (http://dolba.de/htm/loesung_bd8.html) which is sticked to the canopy and a normal "toothpick" antenna placed vertically outside of the fuselage behind the main gear box. However I don't know which is the primary and which the secondary.
