No its not 36-24-36!
Here are some formulas and antenna length tables, either use the formulas to work out the length if if your building a dipole then i've added a chart for laziness. It easy to remember dipole lengths, we know that the antenna is half a wave length long so its not hard to workout. Lets pretend your making a forty meter dipole , the dipole will be half of the wavelength long in this case so its twenty meters wide which intern makes each element half again. 80 meters = 40 meters wide = 20 meters per element.
Here is the formula for and chart for a half wave dipole. 468 ÷ freq (mhz) = Length (feet). The length is often 5% shorter if the antenna is used as an inverted V
7.100mhz | 65' 11"
| 20.09m | 10.100mhz | 46' 4"
| 14.2m | 14.175mhz | 33ft 1/4"
| 10.06 | 18.100mhz | 25' 10" | 7.88m | 21.225mhz | 22' 1" | 6.72m | 24.940mhz | 18' 9"
| 5.72m | 28.500mhz | 16' 5"
| 5m | 50.200 | 9' 4"
| 2.87m

A full wave loop can be worked out using 1005 + freq (mhz) = length in feet. A 5/8th wave vertical can be worked out with 585 / the freq (mhz) = length in feet
