Both the FS3, 3 foot and FS4, 4 foot Firestik II patented tunable tip antennas can be used on the 28.3 - 28.5MHz 10 meter frequency band. To do so, the installer will have to decide where he wants to center the antenna. Upon doing so, refer to the chart and set the antenna accordingly.

NOTES:

  1. Measurements taken at remote sight with lab quality equipment and resonant coaxial cable. All high-low frequencies are indicated at the point where the SWR reached, but did not exceed, 1.5:1.
  2. The tuning screw has a maximum travel of 7/8" (2.2cm).
  3. All low frequency measurements were taken with the screw at 3/4" (1.9cm) out.
