ZS6BKW vs G5RV
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)
