I forget the formula to find the wavelength. Was it the freq divided
by 468 or 234?

Wavelength is 984 divided by the frequency. 468/f is the
length of a 1/2WL dipole and 234/f is the length of a
1/4WL monopole both taking end effects into account.

I thought wavelength was speed of light divided by frequency. ie. 3 x
10^8/freq. Or is the 984 in non SI units?

no..in US they have strange formulas involving feets and inches... (sigh)
nothing to do with established SI

Christine,
when I was young I went to the tool room in East London and asked
for 1 inch round by 6 foot and I was admonished up and down dale for
using the measurement inches. I went back to my lathe and worked it
out all again.
At the tool room I asked for 25mm by 2 metres length of steel only to
find out it only came in six foot lengths! Go to the top of the hill
in Greenwich park at the old observatory and on the wall you will see
examples of lengths from the old days so it was you that started this
mess.
By the way we don't have dual carrageways over here either and we
drive on the other side of the road. I understand Sweden has changed
over now, cars changed over on Sunday and trucks changed over the
following day. That week end is still known as black Sunday I
understand.
