lazy H antenna

[Uncle Ronnie 336]

anyone try this one? this guy on youtube made one with 1/2wave elements with 1/2wave spacing which is the traditional way to go about it. I currently run doublets with 5/8wave elements so what i am thinkin is to preserve my footprint on the map, im gonna do a center feed, 3/8 wave LL feeds to the common point, and use 5/8wave elements and letting my tuner and 4:1 balun at the window do the work of correcting any mismatch that may occur on the antenna or 450ohm LL. hoping this will squeeze more of my juice towards the horizon to pull in australia more from new england.

The W8JK beam antenna is a historically significant, highly effective DX antenna featuring two closely spaced parallel dipoles driven in opposite phase, known for its bi-directional pattern and compact design, making it popular among amateur radio enthusiasts.

Overview​

The W8JK antenna was first built in 1937 by John Kraus, W8JK. It was designed after Kraus studied George H. Brown’s theoretical work on closely spaced dipoles. The original design consists of two parallel dipoles driven 180 degrees out of phase, spaced unusually close together—about one-eighth of a wavelength—which was unprecedented at the time


. This configuration enables a bi-directional radiation pattern

on the one im building im feeding it in the center instead of doing a twisted phase line. makes it more broadband where a tuner will handle it, and i guess improves power transfer.

that w8jk is pretty neat. it appears that both directors do double duty as reflectors if my instincts are correct. a yagi spacing is roughly 1/8~
