suppose is likely to be a VHF yagi not too far removed from 159 Mhz.
My antenna is to be a receiving antenna.

Richard, I thought you wanted a marine-band antenna? The center should be at
156.300 to 156.800 mHz and will cover above that fine, but not well below
it.

Marine band goes up above 160 mhz a bit..If I remember right, the
boats/ patches, etc I used to hear were about 162 mhz. Been a while
though. They were above 160 mhz for sure. MK
