Note: Cable length is measured from end to end of the outer con-
ductor of the connectors, except for UHF and mini-UHF plugs where
it is measured from tip to tip of the center pins.
Note: Dimensions shown are for solid polyethylene cable such as
RG-58C/U or RG-8/U, which have a velocity of propagation 66% of
that of air. If RG-58 or RG-8 type cables with foam polyethylene (v.p. of
79%) are used, multiply the dimensions in the graph by the ratio of the
relative velocities; 79% ÷ 66% = 1.2 in this case.
