Answer: The length of a 5/8 wave antenna for 146 MHz is 4.01 meters.
What is 5/8 Wave Antenna Length Calculator ?
A 5/8 wave antenna length calculator is a tool used to determine the correct length of an antenna based on the frequency you are working with. The length of a 5/8 wave antenna can be calculated using the formula:
where L is the length of the antenna in feet, and f is the frequency in MHz. For example, to calculate the length of a 5/8 wave 2-meter antenna, you simply input the frequency and the formula provides the antenna length.
This type of antenna offers increased gain and better range compared to a 1/4 wave antenna, making it popular for CB radios and VHF applications.
Using a 5/8 wave antenna length calculator can ensure precision in your design, whether you’re working with a 5/8 wave CB antenna or a 5/8 wave 11-meter antenna.
These tools also help in designing matching coils and fine-tuning the impedance to match specific setups, such as in 5/8 wave vertical antennas. Properly calculating and building your antenna leads to improved performance and signal quality.
