k2 balun question

John Cooper
k2/100 10m beam up 30ft with 50ft of rg58 coax.  How many turns and what diameter core to wind a balun on? Plan on winding it on pvc pipe.  If I want to use the kat100 to tune it from 20-10meters do I need to alter the balun?  Ive read 10 turns on 2inch pipe or 6 turns on a 4 inch pipe and Ive also read that the turns don’t matter you have to use 21ft.
