- There are reference points printed on the whip antenna. Adjust the length of the whip to meet your desired frequency according to the reference points.
- Although there are reference points, you might still need to do fine adjustments to the length of the whip antenna until you get a sensible VSWR readings(From an in/external VSWR meter, VNA or antenna analyzer).
RECOMMENDATIONS ON ACCESSORIES
- It’s recommended to have antenna analyzer or VNA to be able to read the parameters of the antenna set up.
