To calculate the Length (\(L\)) of an EFHW antenna:
\[ L = \frac{468}{f} \]
Where:
An EFHW (End-Fed Half-Wave) Antenna is a type of radio antenna commonly used in amateur radio. It is designed to be fed at one end, hence the name, and is typically half the length of the radio wave it is intended to transmit or receive. This design allows for efficient operation and a relatively simple construction, making it popular among radio enthusiasts. The antenna can be installed in various configurations such as vertical, horizontal, sloping, or as an inverted V depending on the available space and specific needs.
Let's assume the following values:
Using the formula:
\[ L = \frac{468}{14} = 33.43 \text{ feet} \]
The Length of the antenna is 33.43 feet.
Let's assume the following values:
Using the formula:
\[ L = \frac{468}{7} = 66.86 \text{ feet} \]
The Length of the antenna is 66.86 feet.
