The formula to calculate the J-Pole Antenna Length (L) is:
\[ L = \frac{468}{f} \]
Where:
A J-Pole antenna is a type of radio antenna that is widely used for its high performance and simple construction. It is named for its unique shape that resembles the letter ‘J’. The antenna consists of a long vertical section, a short horizontal section, and a matching section, which together form an end-fed omnidirectional half-wave antenna. It is commonly used in amateur radio, CB radio, and FM broadcasting due to its ability to provide a strong, clear signal over a wide range of frequencies.
Let's assume the following value:
Using the formula to calculate the J-Pole Antenna Length:
\[ L = \frac{468}{144} \approx 3.25 \text{ feet} \]
The J-Pole Antenna Length is approximately 3.25 feet.
