How To Work Out Wavelengths
---------------------------
Speed of light % by Frequency = Wavelength in Metres
Ie,
0.3 % 2.4gHz = 0.125 metres (12.5cm) % by 4 to get 1/4 wave....0.03125 metres or 31.25mm
Or for 1.2gHz,
0.3 % 1.2 = 0.250 (25cm) % 4 = 0.0625 or 62.5mm
0.3 was used as that is the speed of light in air.
Also try to use the full frequency Ie, 2.43 instead of 2.4 it makes a small difference to look at at quarter wave but it would be more noticable at full wave,
0.3 % 2.43 = 0.123 or 12.3cm....2mm difference

Ps,
% = divide by, and yes,
For the purists if you are running a length of cable you need to add a few more equations, but Heh, lets show people how to walk first :-)
