Here are the dimensions
1005/28.3 x 12 x 2.54/100 = 10.82m
1/4 wave = 2.7m
1/3 wave = 3.60m
1/12 wave = 0.9m
I had a 3m piece of 75ohm coax with an N connecttor and F connector. I measured the Vf of the cable as 0.8 using the MFJ259B.
1/4wave coax at 28.3 = 10.82 / 4 * 0.8 = 2.16m
I cut the F end off and bared the wires of the coax That went into a chocolate block and joined to the end of the loop wire. I strung it up on a 5m pole and used some lengths of string to pegs in the ground to hold out the shape. The 75ohm coax is held on the pole with some double sided velcro. There’s a loop mid way along the bottom of the wire to tie that to the pole to stop it waving about in the wind.
Feed is 50ohm coax from the 75 ohm quarter wave transformer to the radio (or MFJ in this case).
Now for a chance to see how well it works.
