It would be pretty much the same as with twinlead.Rabbit73: How do you calculate the length of a folded dipole using 14AWG? Thank you.

Channel 2 is 54 to 60 MHz; center freq is 57 MHz

5540 divided by 57 = 97 inches

Thats easy math.It would be pretty much the same as with twinlead.

Where does 5540 come from? Thank You.

Radio waves travel at the same speed as light waves, which is a constant calledThats easy math.

The speed of light in vacuum, commonly denoted

The length of a halfwave dipole can be calculated in meters, feet or inches.

Mathematical Applications

λ (lambda) = c/freq

The length of the antenna is less than the free space length because of the "end effect."

Dipole Antenna Length: Calculation & Formula » Electronics Notes

The end effect is larger for VHF and UHF antennas because of the length to diameter ratio. Using the inches formula and the correction factor of 0.94:

5905 x 0.94 = 5550

Empirical tests show that 5540 works best in practical TV antennas:

5540 divided by 57 MHz = 97.2 inches

Im good at math but, WOW. Good read.Radio waves travel at the same speed as light waves, which is a constant calledc:

The speed of light in vacuum, commonly denotedc, is a universal physicalconstantimportant in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s).
