This presentation compares
two dipoles configurations with the primary focus being adjustment of
Standing Wave Ratio (SWR) to match a modern solid state transceiver with an
internal autotuner.The results are
studied using antenna design software adapted from the MiniNec version called
MMana Gal.
The ZS6BKW antenna
configuration is a very good choice for a beginning ham radio operator who
wants to get on the air quickly and effectively on the HF bands and who may
not have a tuner or autotuner.It also
will put more RF energy in the air and dissipate less in the coax, especially
if the coax is not of the highest quality or when operating in the 10 meter
band.
The antennas were chosen for
their low cost and availability.Each
can be built by the average amateur for a total cost of less than 50 dollars
(US).In addition, each antenna can be
modified and transformed into the other antenna configuration with minimal
effort.(Add or subtract wire or
matching ladder line length)
