the ham big-mac does work very well, i had a mac on a 73ft mast in a field, it performed a little better than a stock sigma4, against a modded vector im sure it would be a close contest,

its not all one sided, the 5/8 over 1/4wave mac seems to have a narrow beamwidth,
in any winds the big-mac tx and rx signal sways like you are mobile with a floppy whip when compared to the much stiffer stock sigma4 on the same mast,

the big-mac is weakly constructed, a much stronger stiffer version would be great but expensive unless you are into homebrewing,

at over 32ft tall with two coils a basket and 6 1/4wave radials for birds to sit on while shitting all over your yard/house its big and ugly to some people,

i wish i still had mine to take measurements for an i10k > big-mac conversion
