Half wave dipole antenna?

In free space it's 492 divided by the frequency in MHz. However, there is no such thing as free space in the real world so the better and more accepted formula is 468 divided by the frequency in...

The length of a quarter wave for constructing one end of a dipole is:234/MHz = feet of wire.For instance if you have an 80 meter ham radio transceiver and want to construct a dipole to match a...

936/Frequency = Length (Full wave) 468/Frequency = Length (Half wave) 234/Frequency = Length (Quarter wave)

E=sin(Theta);You need to normalize the equation for the electric field of the half-wavelegnth dipole. recall E=sqrt(ExE*) where E* is the conjugate of the E field.This is why you only get an eight...

A: At a particular frequency it could be zero. but the impedance is nearly 2000Different answer: I built a 1/2 omni antenna for 20 meters (14.3mhz). To keep the impedance 50 ohms, I used the standard...
