5.2 Telescopic Whip Adjustment
After selecting the frequency band with the wire lead, fine-tune the antenna by adjusting the length of the telescopic whip. Extend or retract the whip until the lowest Standing Wave Ratio (SWR) is achieved for your specific operating frequency within the chosen band. The following table provides approximate starting lengths for the telescopic whip for various frequency bands. These measurements are approximate and may vary based on installation environment and vehicle.
