This might help on a small lot: I am very fortunate to have a dual rx K3S and I
am planning to use 2 flags at right-angles in the corner of the field I've been
loaned. Being in the bushes and at modest height they cannot be seen and with
relays to change phase of each I hope to get 4 quadrants in diversity
reception. I chose the flag as deliberately lower performance than some others
to avoid a hole around 45 degrees, ie to complement diversity and they have a
good f/b according to lists I've seen. Everything is a compromise. I suppose
a K9AY could be used in diversity with suitable connections.
