There really isn't a down-side to the 105CA. The 105BA was designed at
least 15 years ago, long before advent of optimizing antenna software.
Hy-Gain got the antenna to produce reasonable gain but never really
optimized it. After K6STI released YO, I wrote an article for the
NCJ describing YO and used the 105BA as an example of what could be
done to improve an existing yagi. The gain, F/B, and SWR bandwidth
were all improved over the stock antenna. The dimensions of the 105CA
are fairly close to the NCJ article. Hy-Gain now uses YO and other
antenna modeling software to tweak their antennas before they take
them to the range.
