KAZ: Included in my voluminous measurements this summer was a set of data taken with various height-extensions of the null-side support pole. I got this idea from the way some AM Directional-Antenna systems are designed with un-equal tower heights.
Can you run a few EZNECs assuming a front pole height of 22 feet with a few different “back”-pole heights? We may discover that identical-apex is the best solution. On the other hand… Cheers!

This is because a double loop is nearly electrically the same as an end fire array of two single loops. 73 KAZ On Wed, Oct 24, 2018 at 1:27 PM Mark Pettifor < <mailto:[email protected]> [email protected]> wrote: > Well here's something that's been on my mind lately, regarding > differences between superloops and the DKAZ: > > It seems to be my experience so far that at night, the back and side > nulling characteristics of these antennas changes, due to sky wave vs. > ground wave, yes?
