The rest is straight forward as you now know the velocity factor of the coax.. 360 deg =1 wave length therefore 180 degrees (half wave) = 468/1.85 * .879 = 253 * .879 = 222.4ft Therefore 1 degree of that coax at 1.850mHz = 222.4/180= 1.23ft so your 84deg line is 1.23 X 84 = 103.32ft = 103ft 4ins and your 71deg line is 1.23 X 71 = 87.3 ft = 87ft 3 1/2ins these figures are only examples as vf is/was incorrect
