Bob: Are there published documentation on the difference in gain between horizontal and vertical polarization in VHF frequencies? At most amatuer freq. range, I didn't notice significant problems communicating between the two. Do you happen to have the formulas handy for both the j and the dipole? I guess the best cut would be for Ch16. What are the dimensions for each? If you've got the fomulas handy, that is. > >The easiest antenna to use in the field is probably a J-Pole made from coax >and twin lead for pennies.

I was thinking about carrying a spare antenna in the even I was stranded somewhere...rather than trying to errect a whip on the boat itself.
