I'm looking to make the center frequency 159 Mhz. So any practical

I
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.

I'm following two threads with my antenna muses, I don't know which one is
going to come out on top:

engaging in applying scaling, and tackling what is required when changes are
made in element diameter and boom size of a tried and tested *practical
design* one that employs a metal boom,

or following the track that seems to involve simply scaling with a *model*
and the making of other adjustments to the model, (arising from element
diameter changes) where in practical terms the model is sufficiently
equivalent to a "practical design" by virtue of the employment of a non
conducting boom in the construction of the yagi.

But to your point:

Marine band is from 156-162 Mhz. Center 159 Mhz.
