When building an antenna to figure iut length such as a wire or dipole you would use 468 / frequency where you want it to work. Such as if you us channel 38 you would do this 468 / 27.385 = 17 feet is what you get.

As far as coax Ive heard so many theories like its gotta be in increments of 3 feet or 25 feet but yet I have used 2 foot if not shorter pieces and made jumpers with no trouble so there is indeed a mystery in there somewhere I just havent found it or experienced it.
