- Hi TT'ians I got my 3 vertical array up and running Sunday and it seems to be working pretty slick, switchable in 6 directions. I am using a 1/4 wave phasing line. I have misplaced my ON4UN Low Band

- 135 degrees = 3/8 wavelength, right? 50% longer than a 1/4 wave. It's easiest to look for half wavelengths.. 1/4 wave at 7MHz is 1/2 wave at 14 MHz. but you want 50% longer.. 3/2 length = 2/3 frequen

- Hi Jim Don't know where my '1/4 wave on the end of a 1/2 wave' came from :-) It's 3/8 wave not 3/4 wave. Brain fart I guess. Thanks for straightening me out and 73 Tom W7WHY Thanks __________________

- You won't get 135 degree phase shift between two phased verticals using a 135 degree phasing line. The mutual impedance between the two verticals causes it's own phase differential. ON4UN's book show
