An Easier way to calculate Dipole length

How to get the RIGHT length for your dipole!

I cannot tell you how many times I have tested and cut, tested and cut, tested and cut TOO SHORT when trying to get a dipole the right length. If you have ever done the same you know how frustrating it can be.

Well, Ian Keyser, G3ROO, the Aurthur of Practical and Tested
Aerial Systems has a very easy way to get the right length for your Dipole
every single time!

>From Ian, G3ROO -
"Make dipoles too long and erect it, now measure the
length and resonant frequency (with GDO or analyzer)  and multiply them
together,   Divide this figure by the {your} required frequency and it will
give you the correct length of the aerial."

Now. How simple is that? Buy that book, by the way, if you ever get the chance.
It is awesome.
