Thanks, I stand corrected. Personally, I consider that display to be like eye candy, to lure the buyer, but its there for sure. I've read the patent a few times, but I don't recall it appearing there, but I could have missed it.

 

Like I said earlier, Sirio refers to the NTO as a 1/4 wave ground plane in their manual, so that is good enough for me.

 

To tell the truth though, a 1/4 wave ground plane with horizontal radials at 48' feet does look to make a pattern very similar to my pattern for the NTO @ 48'. So, even though I tried, I guess I can't really support my point the the A/P, and the NTO, are 1/2 waves.
