Difference Between UHF and VHF Antenna: Choosing the Right Frequency for Your Application
May , 28 2025
What Is a VHF Antenna? VHF antennas operate within the Very High Frequency range of 30 MHz to 300 MHz. These antennas are commonly used in: FM radio broadcasting (88–108 MHz) Marine radio communication (156–174 MHz) Aviation communication systems Emergency and amateur radio operations Due to their longer wavelengths, VHF antennas perform well in open and rural environments where line-of-sight cove...

What Is the Difference Between a Power Divider and a Power Splitter?
Jun , 18 2025
1. Basic Function — What Do They Both Do? At a high level, both power splitters and power dividers are passive RF components designed to: Take one input signal Split it into two or more output signals Maintain specific impedance (typically 50Ω or 75Ω) Preserve signal integrity as much as possible These devices are commonly used in test setups, antenna feeds, distributed antenna systems (DAS), and ...

What Is the Input Impedance of a Log Periodic Antenna?
Jul , 12 2025
Log periodic antennas are widely used in RF communication due to their broadband capabilities. One critical aspect of their performance is input impedance, which determines how efficiently the antenna transfers power from the transmission line. Understanding this parameter is essential for engineers and hobbyists working with these antennas. Why Input Impedance Matters The input impedance o...
