Design a J-Pole Antenna for your Packet Radio Station





NOTE: Coax center conductor attaches to the "Long section" feed point.
Shield attaches to the short section feed point.

Calculate the length for each "J" pole dimension.
A (Long section) = 705 / F (MHz)
B (Short section) = 234 / F (MHz)
C (Feed point) = 23 / F (MHz)
D (Spacing) = 22 / F (MHz)

Enter a number for calculating dimension "A, B, C, or D".
Divided by Freq MHz
This dimension expressed in feet is: .
This dimension expressed in inches is: .
This dimension expressed in meters is: .
