And I went from the K9AY loop to the Hi-Z 4 square. While the K9AY put
more low band DX in the log than the TX antenna did, I seemed to hit a
performance plateau after a year or two. The 4 square from Hi-Z was
hundreds of dollars less than a similar competing product and the
several db of benefit it brought quickly added 20+ countries on 160.
My neighbor permits me to install the 4 square in his hay field in
October and I remove it in early April or whenever the ground thaws.
As an intermittent operator, in the shack when family and jobs permit,
the Hi-Z has added much to my enjoyment of the low bands and I spend my
summers wishing for winter so the array will be back in service.
The Orion likes it too!
