In search for a good fieldday style 40m
antenna I chose the moxon principle to create a light yagi antenna,
which could be mounted onto our fieldday tower.
The
elements are built of the lower sections of 12m fiberglass poles by spiderbeam
(DF4SA). The middle section is a 1m long aluminium tube
(60x2mm).
The
antenna itself is made of DXWire
from DK1RP.
The
elements have to be guyed in every direction.
See
the following pdf for measures: Antennas/moxon_7mhz.pdf

The 40m Moxon is mounted on top of the crank up tower. Above sits an
A3S

close-up
of the "boom-section". the thin element above is used to
hold the cable and support the feedpoint.

one of the Moxon supports made of spiderbeam poles and an aluminium
tube to connect the element halves. (the picture shows DJ5MW, DK5MD
and DG4BUL)
