lord loh. said:What is the difference between the two antenna parameters - Gain and Directivity
Which is practical (not considering the ideal case of isotropic radiators)?
Nigel Goodwin said:The standard to compare against is a 1/4 wave dipole.

Half wave Nigel, each "leg" of the dipole is 1/4 wave, the overall length is half wave.
mstechca said:While we are on antennas, Isn't it true that if the length of the antenna is equal to the wavelength of the frequency to be received, maximum gain (or sensitivity) is achieved? or is wavelength defined for some other reason?
For example, If an antenna is 2 meters as opposed to 1 meter, and the frequency of interest is 144Mhz, is maximum gain (or sensitivity) achieved?
