length

I am building a dipole antenna. I know that the feedline needs to be approximately 1/2 wavelength in length (or factors there of) for best SWR. However, there is one item of confusion. I am making an RF choke by coiling the feedline at the base of the antenna. Do I include the length of coax in...

Does length matter? If the antenna is an All-Band 25-1300MHz antenna is the length just personal preference? Does performance vary by length? From 1 2/3" up to 17" all specify All-Band coverage from 25-1300MHz. Logically, I would think the longer length would get better coverage and clarity...
