But actual lengths are non-critical. You can use a tape measure or a
wooden ruler. And don't worry if you can't find your spectacles.

Hook, line, and sinker!

and also the dipole is shorter because you want to cancel out the reactance.
a "real" half-wave would have a resistive and reactive component.

i think if you get into big tubing or pipe, you get too much reactance.

The theoretical resonant length of a 1/2-wave dipole is 150/F metres.

i should have thought of that.

c = 3 * 10^8 m/s
F = frequency / 10^6

465/F theoretical (feet)
468/F practical

i think i made a math error.
