Aloha,
One of the OT's out here, Sam, KH6AFS, at Hilo Town puts
out a Snake antenna at many of the field events here. Last
was on 9/27 for a QRP outing. Anyway, the purpose for him
is to listen to mainland BC stations between 500 and
1700 kHz. He claims it also works on 160 and 80. It is
not usual to hear BC from the mainland in Hawaii!
It is a piece of 52 ohm coax, about 200 feet long.
At the rcvr, the inner conductor goes to the antenna
connector of the rig, the shield is left floating.
At the far end, a 52 ohm resistor ties the inner
conductor and shield together. The coax lays out
across the ground, in this case running about
North and South, as KH6AFS says it is most
sensitive on the broad side of the coax.
It does work. I assume this has to be a different
idea than a Beverage, as the Bev is most sensitive
along the direction it is strung out.
He also claims one can transmit with the Snake, but then
you leave the 52 ohm terminating resistor off.
Is this just a fluke, or really something to look into
more carefully??
73, Jim, KH7M
