I was just getting ready to stick up a Hygain 105CA fixed south this
weekend and for kicks I decided to adapt NW3Z's OWA design to the HG105CA
antenna. I added a single element, making the antenna now six elements,
and kept the same boom length of 24'. I have stuck the AO file at the
link below, if anyone is interested.
6 Element modified HyGain 105CA on a 24' boom.
Segmentation Density: 30 segments / halfwave
28.0Mhz F/B=26.33db Gain=9.88 SWR=1.04
28.4Mhz F/B=36.55db Gain=10.03 SWR=1.06
28.8Mhz F/B=23.67db Gain=10.03 SWR=1.22
29Mhz F/B=22.19db Gain=9.92 SWR=1.75
