[50mhz] antenna 2m/6m vertical

[Chris Boone]

When the band is open Al, anything will work...but for normal SSB use,
horizontal is best...Vertical is for FM of course...if the band is NOT open,
you do see a 20db or more loss between polarizations.....but when the band
IS open, anything goes (I once worked a 6m opening on a 220 mag mount NLA
antenna on a metal chair!! :)
