           	| 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
