Design a J-Pole Antenna

A = long radiating element
B = short stub element
C = distance to feed point connections
D = distance between elements

NOTE: Coax center conductor attaches to the long "A" section feed point. Coax shield attaches to the short "B" section feed point.

Enter the operating frequency in MHz to calculate the dimensions for your J-pole.

(Freq MHz)

Length of A: inches.
Length of B: inches.
Length of C: inches.
Length of D: inches.
