[TowerTalk] 160 meter receiving loop antenna schematic has beenposted

[Richard (Rick) Karlquist]

Various references give numbers ranging from .08
to .15 wavelengths circumference.  Before you reach
this, you may find that the loop is resonant below
80 due to the coax capacitance.  I would recommend
3 ft corner to corner as a start.
