Some great information about coax lengths and swr

thanks Doughboy , thats easy enough to understand!

but im sure someone will chime in to contradict that explanation
as they always do.......

"Here is how to figure out your true 1/2-wave:
492 x (Velocity Factor) / Frequency (MHz)
For example, I want to figure out the true half wave coax length for RG-59/U (foam) on my home channel (ch. 33 - 27.335):
492 x .79 / 27.335 = 14.219 feet
Now add 14.219 to itself to determine your 1/2 wave multiples. Remember to use every other number. See the example below:
14.219 feet 1/2-wave multiple, 28.438 feet 1-wave multiple, 42.657 feet 1/2-wave multiple, 56.876 feet 1-wave multiple, 71.095 feet 1/2-wave multiple, 85.314 feet 1-wave multiple
and so on . . . .
Use only the lengths that fall on the 1/2-wave multiples and you will be all set.

if im understanding what he's saying ... hes saying 1 or 2 or 3 electrical wavelengths don't work to get the effect he's talking about , but 1/2 , 1 1/2 , 2 1/2 etc. will . it's my understanding that a electrical half wavelength or any multiple of that length for that frequency will work .

doughboy , can you supply a link to the article ?
thanks
