The elevated wire vertical antenna for ten meters is simple and effective. Named it
a "tripole" just for fun.
The
antenna itself is simple. A piece
of RG-58 cable runs to the feed point of the antenna,
and is attached to an insulator. Two radial
wires are soldered to the coax-line braid at this point.
Another piece of wire forms the radiator. The top of
the radiator section is suspended from a tree limb or other
convenient support, and in turn supports the rest of the
antenna. The
dimensions for the antenna are 234/f. All
three wires of the antenna are ¼ wavelength long. The
tree-mounted vertical idea can also be used for fixed
station installations to make an invisible antenna.
Shallow
trenches can be slit for burying the coax feeder
and
the radial wires. The radiator itself is difficult to see
unless
you are standing right next to the tree.
