ok antenna gurus what
did i do wrong? originally the swr on this 4 el Hygain 6 mtr beam was a
perfect 1:1 at 50.1 . But I wanted to run high power thru it so the
manual calls to change the coax balun from rg58 to rg213 which i did
except I think that the coax was RG8. It was cut to the same length as
the 58 as per the manual. Now the swr at 50.1 is 2:1 and the resonant
point for 1:1 is clear up at 52.0 . I don't want to change the element
lengths as they should be right on. Only thing else is move the beta
match in or out some.... or match it some other way. Would the 213/rg8
make that kind of difference? Maybe I should change the length of that
coax! Ideas? help!!!! lol, Cort K4WI
