All I need now is the plans for the antenna but I should have those

In about as long as it takes to go to the 'VHF/UHF Long Yagi Workshop'
on the site below. Some other questions will be answered there too.


Been there, done that. Couldn't find the measurements for the 4 wavelength
version. I have them now though from SV5BYRs site

Certainly a shorter sub-boom centred on the balance point is one good
way to go. Another is to use quarter-inch larger square tube for the
middle section, with the inch-square boom running right through, and
hard aluminium shims driven into the end. Don't forget to use a larger
boom correction for that centre section.


thanks for the advice.
It is much appreciated.
The only question I have now is probably a daft one but here goes....... the
plans for this antenna specify that the reflector should be at position 0 on
the boom and D13 should be at 8300mm relative to the position of the
reflector.. Where would one drill the hole for the reflector ? i.e how far
in from the end of the tube, and how far past the hole for the last director
would the boom actually end ?
