You can download a program that does all calculations for you, be it yagis,
dipoles, verticals or what..

Have a look at http://www.sm2cew.com/download.htm

You will find the VK3UM Site and Radiation Calculator version 5.1
(EMRCalc.exe) if you scroll down the page a bit.
The program does not need an install, just run the EXE-file. 

When it comes up it is in VHF/UHF/SHF mode, click a small box marked "HF"
in the "Frequency" box to get the HF options and antennas.

Different radiation limits (standards for different countries) can be chosen.
