Compare Bi-Quad Performance
Compare Bi-Quad Performance to other Antennas.

Mclapp M4 (10x9.5) 4-Bay provides the best Raw Gain, with CM4228HD close behind, except for
additional Gain Loss on lower channels (which might NOT be that much, see CM4228HD results).

Stacked 8-El FD-Yagis (with 2 Reflectors each) provides better Raw Gain and esp. F/B & F/R Ratio
than the 15-El "Double-Quad" Yagi (Stacked 8-El Yagis, except one common Bi-Quad replaces
two Active Elements).

7-El Quagi and 7-El Bi-Quad Yagi provide lower Raw Gain (as expected) but with minimal
F/B & F/R Ratio performance on mid-band and higher freqs.

EDIT (27Jun2013): Updated Comparison Chart with improved results for Stacked 8-El FD-Yagis (w 2-Reflector Rods).

EDIT (4Jul2013): Added two Comparison Charts, including 8-El FD-Yagi (2RR) and 8-El Bi-Quad Yagi (2RR).
