[TenTec] Value of RX Only Antennas

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!
