HiVHF 13El FD-Yagi - Stellar Labs 302476

Hi-VHF 13-Element Folded Dipole Yagi, including 4 Reflector Rods, MCM Stellar Labs 30-2476,
analyzed using 4nec2. Dimensions were provided by user [majortom].

HiVHF Raw Gain = 9.8 to 12.5 dBi, F/B & F/R Ratio = 15 to 25 to 17 dB [Good to Excellent]
and SWR (300-ohms) is Under 2.7 [Excellent].
That is 0.9 to 1.7 dB higher Gain and much better F/B & F/R on low Channels than than S-L 30-2475 9-El FD Yagi.
