OPEK CX-5 Coaxial Antenna Switch 1KW PEP Rated 3 Position

Opek’s CX-5 is a 3-position coaxial switch designed for high power applications, with one input and three outputs. It operates across a frequency range up to 500 MHz, which covers typical VHF/UHF bands used by HAM and CB setups. The kit includes mounting hardware (mounts and screws) for straightforward installation. Suitable for operators who need robust switching for multiple antennas or RF feeds without compromising signal integrity. Consider its 1 kW PEP rating when planning high-power experiments or transmit tests in legal and safe operating contexts.
Anteenna TW-102BLUE 2 Position Coaxial Switch

The TW-102BLUE from Anteenna offers a two-position coaxial switch with a broad DC to 1 GHz frequency range, making it suitable for both CB and HAM bands. It uses SO-239 (UHF Female) connectors plated nickel, providing reliable contact surfaces and corrosion resistance. This model is compact and suited to portable or home setups where a quick swap between two antennas is beneficial. Its simple two-position form factor minimizes complexity while delivering dependable switching for mixed-use radios.
Anteenna TW-102 2 Position Coaxial Switch

This 2-position Anteenna switch uses SO-239 (UHF Female) connectors with a golden-plated finish for enhanced contact and durability. Like the BLUE variant, it covers DC to 1 GHz and maintains a 50-ohm impedance for consistent RF performance. It’s well-suited for boatloads of small to mid-range setups where a reliable, simple switch between two antennas is needed without a large footprint.
Dosy Antenna Selector Switch SW-4

Dosy’s SW-4 is a compact antenna selector designed to handle up to 1,000 watts, with low insertion loss and a professional PCB-based architecture. It supports multiple feed paths and is suitable for more demanding amateur setups where stable power handling and minimal signal loss are essential. The 1000 W rating makes it a candidate for high-power demonstrations or field operations within legal transmission limits and safety practices.
2 Way CB/HAM Antenna Coax Switches SO239-100W

This 2-way coaxial switch from DmgicPro covers a broad frequency range (0-30 MHz) and uses SO-239 UHF female connectors. Its two-output configuration supports seamless switching between two antennas for amateur radio operations. The device emphasizes a balance between simplicity and broad-band capability, making it a practical choice for basic two-antenna setups at home or in the field.
Anteenna TW-103 3 Position Coaxial Switch

The TW-103 from Anteenna adds a 3-position option, expanding from two to three outputs. It maintains a DC to 1 GHz range with SO-239 female connectors in a golden-plated finish for reliability and longevity. This model is suitable for more complex station setups where three antennas or feeds need rapid switching without sacrificing signal integrity.
Anteenna TW-103Ni 3 Position Coaxial Switch

This Ni-plated variant of the TW-103 provides corrosion resistance with a similar frequency span (DC to 1 GHz) and 50-ohm impedance. The Ni finish improves durability in challenging environments, making it a solid choice for outdoor stations or mobile installations where exposure to the elements may occur.
Anteenna TA-102BLUE Color 2 Position Ham Coaxial Switch

The TA-102BLUE offers a blue variant for visibility and style with a 2-position configuration. It features a DC to 1 GHz range, SO-239 UHF female connectors, and 50-ohm impedance. This model is suitable for hobbyists seeking a lightweight switch with straightforward operation and a distinct look for their station rack or portable kit.
Buying Guide: Key Considerations for Choosing a CB Antenna Switch Box
- Power handling and wattage: Match the switch’s power rating with your transmitter output. Higher-power setups require switches rated for higher wattage to prevent arcing and damage.
- Frequency range: Ensure the switch covers the bands you operate. Some models are optimized for DC to 1 GHz, while others focus on VHF/UHF ranges typical for HAM or CB operations.
- Number of ports and positions: Determine how many antennas or feeds you need to manage. 2-position switches are simple; 3-position and multi-port options enable more complex setups without extra hardware.
- Connectors and impedance: Most switches use SO-239 (UHF Female) connectors with 50-ohm impedance. Confirm compatibility with your cables and antennas.
- Construction and durability: Consider plating (gold, nickel, Ni) for corrosion resistance and durability, especially in harsh environments or mobile installations.
- Installation and footprint: Smaller PCB-based designs are convenient for home benches, while rugged metal housings suit outdoor mobile operations. Check mounting hardware and screws included.
- Signal integrity: Look for switches with low insertion loss to minimize RF power loss during switching and ensure clean handoffs between antennas.
- Safety and compliance: Use switches within legal transmission limits and adhere to manufacturer guidelines for high-power operations to avoid equipment damage or safety hazards.
