Obviously the end-fed radiator does need something to push against, like all antenna radiators. If no choke balun is installed at the transformer, the radiator will simply use the coax as counterpoise - the coax . The two secondary transmission lines also have different widths and lengths. This arrangement provides an imbalance between the widths and lengths of the transmission lines. Jack, VE3EED ( SK ), has also made this calculation.

They differ slightly because VE3EED used the center of the bands in his calculations, while AB3AP used . Trifilar means that there are three wires wound simultaneously around the core.
