These diagrams show an antenna that should be easier to construct, and
requires less material, and does not require any balun. The diagram at the
left shows one view of the antenna . It is basically the same as the one that
I demonstrated at the last club meeting, except that it is a little longer, and
does not require the other coax fittings, except the one that connects to the
HT (radio) .
Each wire element is 17.5 inches, and the center connector of the coax
connectors to the similar side wire element . The coax in the center is split
off-center , with 18.5 inches on one side , and 11 inches on the other side .
The coax center connectors all connect together; and the shields all connect
together ( at the feed point ). This will give the antenna a deep null on one
side, which should be better than the one given in the copy of the radio
book I gave you .
