Building a wire delta loop for six meters is quite simple.
Loop calculation, 1005 / 50.255 = 19.99 feet = 6.09 meters.
For a coax matching section I used what I had in the box of old coax off cuts, RG62 a/u (93 ohm, VF = 0.86).
The quarter wave matching section calculaton, (246 x 0.86) / 50.255 = 4.209 feet = 1.28 meters used as an “ugly balun” rolled up on a length of 50mm PVC drain pipe (white).
The calculations appeared to be correct and the antenna resonates well!
