Frequently Asked Questions
Q: What frequency range does this 4-way coax remote antenna switch support?
A: This RF antenna switch operates across a frequency range of 1.8 to 60 MHz, making it suitable for HF amateur radio bands, shortwave broadcasting, and other applications within that spectrum.
Q: Can I use this antenna switch with high-power radio transmitters?
A: Yes. The switch is rated for up to 500W PEP (Peak Envelope Power) continuous operation, making it compatible with high-power transceivers used in amateur radio stations and broadcast environments.
Q: What connector type does this switch use, and is it compatible with standard coaxial cables?
A: This switch uses SO-239 (UHF Female) connectors, which are standard in amateur radio setups. They are compatible with PL-259 plugs found on most common coaxial cables, allowing for a quick and straightforward installation.
Q: How is the remote switching controlled?
A: The switch uses a +12V DC control voltage via the included controller kit. This allows you to remotely select any of the four antenna inputs from your operating position without physically accessing the switch unit — ideal for antennas installed at height on towers or rooftops.
Q: What is the impedance of this RF antenna switch?
A: The switch is designed for a standard 50 Ohm impedance system, which is the most common impedance used in amateur radio and RF communications equipment.
