Review MFJ 1704 Position 2.5kw 0-450 Mhz Antenna Switch

The **MFJ-82010** is a high-performance, multi-band antenna switch designed for serious radio enthusiasts, contest operators, and DXers who demand reliability, flexibility, and precision in their station setups. This robust **1704-position switch** is engineered to handle up to **2.5 kW of continuous power** across a wide range of frequencies, making it an ideal choice for both amateur radio operators and commercial applications requiring seamless switching between multiple antennas. With a **0-450 MHz operating range**, the MFJ-82010 excels in managing signals from HF through VHF/UHF bands, including popular modes like CW, SSB, FM, and digital communication protocols. Its **solid-state construction** ensures durability and low insertion loss, minimizing signal degradation while maintaining high isolation between ports to prevent interference and cross-talk. The switch features a **durable, front-panel-mounted selector knob** with clear, backlit numerical indicators, allowing for quick and intuitive operation even in low-light conditions. Additionally, the MFJ-82010 includes **built-in protection circuits** to safeguard against voltage spikes, overcurrent, and reverse polarity, extending the lifespan of both the switch and connected equipment. Whether used in a fixed station, mobile setup, or portable deployment, this antenna switch delivers exceptional performance with minimal maintenance, making it a trusted workhorse for operators who prioritize efficiency and versatility in their radio communications.

### **Pros and Cons of buying a MFJ-82010 3-Band (1704 Position) 2.5kW Antenna Switch**

1. **High Power Handling** Rated for **2.5kW continuous duty** (5kW peak), making it suitable for high-power HF and VHF/UHF operations, including contesting and DXing.

2. **Wide Frequency Coverage** Supports **1704 positions**, allowing for extensive antenna diversity (e.g., multiple HF bands, VHF/UHF, or even satellite bands).

3. **Reliable Construction** MFJ is a well-known brand in amateur radio with a reputation for durable, well-engineered equipment.

4. **Flexibility for Multi-Band Operations** Useful for stations running multiple antennas simultaneously (e.g., vertical dipole Yagi) without manual switching.

5. **Compatibility with Common Antennas** Works with most coax cables (RG-8, LMR-400, etc.) and connectors (PL-259, BNC).

6. **Relay-Based Switching** Mechanical relays ensure clean signal transfer with minimal loss or interference.

7. **Modular Design** Can be expanded with additional modules if needed (though the 1704 position model is already highly configurable).

8. **Good for Contesting & DX** The high power rating and flexibility make it ideal for competitive and long-distance operations.

1. **Expensive** Priced significantly higher than basic 2- or 4-position switches, which may be overkill for casual operators.

2. **Bulkiness & Space Requirements** A 1704-position switch is large and may not fit neatly in small shacks or mobile setups.

3. **Complexity in Setup** Requires careful wiring and configuration, especially if integrating with multiple antennas or automation systems.

4. **Potential for Wear Over Time** High-power switching can stress relays, though MFJ s quality should mitigate this.

5. **Not Ideal for Low-Power Users** If you rarely exceed 100W, a simpler switch (e.g., 2- or 4-position) would suffice.

6. **Limited Built-in Protection** Unlike some modern switches, it may not include built-in surge protection unless added externally.

7. **Compatibility Issues with Some Antennas** Some high-impedance or specialized antennas may require additional matching networks.

### **Conclusion & Recommendation**

The **MFJ-82010 1704-position 2.5kW antenna switch** is an excellent choice for **serious amateur radio operators** who need **high power handling, extensive antenna diversity, and flexibility** for multi-band or contesting operations. Its reliability, wide frequency coverage, and robust construction make it a strong investment for those who demand performance.

However, it is **not necessary** for **casual or low-power users** who only need basic switching. For such operators, a **simpler 2- or 4-position switch** (e.g., MFJ-820, Diamond X300) would be more cost-effective and sufficient.

- **Buy it if:** You operate at high power (500W ), run multiple antennas simultaneously, or engage in contesting/DXing.

- **Skip it if:** You primarily use one or two antennas at low power and prefer a more affordable, space-efficient solution.

For most home stations, a **mid-range switch (e.g., 8- or 16-position)** strikes a better balance between flexibility and cost. The MFJ-82010 is best reserved for **high-end setups** where its capabilities are fully utilized.
