Review MFJ Position Antenna Switch Connector Doesnftt Accept

The **MFJ MFJ-1702CN Position Antenna Switch Connector (PL-259)** is a high-performance, dual-position antenna switch designed to provide seamless switching between two antennas with minimal signal loss and maximum reliability, making it an essential component for amateur radio operators, emergency communicators, and professional two-way radio systems. Engineered with precision, this switch features a robust **PL-259 (UHF) connector interface**, ensuring a secure and stable connection that resists corrosion and maintains signal integrity even in demanding environments. The **rotary position selector** allows for effortless switching between two antennas, with a tactile feedback mechanism that confirms each position change, reducing the risk of accidental misalignment during operation. Built to withstand frequent use, the switch is constructed from durable materials, including a sturdy metal housing and high-quality internal components that minimize signal degradation and prevent arcing or interference. Whether deployed in a fixed station, mobile setup, or portable configuration, the MFJ-1702CN delivers consistent performance across a wide frequency range, from VHF to UHF bands, making it ideal for applications such as beam antenna switching, diversity reception, or emergency backup systems. Its compact yet rugged design ensures easy installation in tight spaces, while the clean, professional finish enhances its aesthetic appeal without compromising functionality. For operators seeking a dependable, low-loss switching solution that combines ease of use with long-term reliability, the MFJ-1702CN is an outstanding choice that elevates both performance and convenience in any radio setup.

### **Pros and Cons of buying a MFJ-1702CN Position Antenna Switch with PL-259 Connectors**

1. **Versatility in Antenna Management** The MFJ-1702CN is a 4-position antenna switch, allowing you to connect up to four different antennas (e.g., vertical, dipole, Yagi, or beam) to a single transmitter. This is particularly useful for portable operations, multi-band setups, or when switching between different antennas without retuning.

2. **Compact and Portable Design** The unit is relatively small and lightweight, making it ideal for field day, portable operations, or mobile setups where space is limited.

3. **Built-in Protection** The switch includes built-in protection against reverse polarity and high voltage, reducing the risk of damaging your radio or other connected equipment.

4. **Easy Installation** The PL-259 connectors are standard and widely compatible with most coax cables and antennas, simplifying setup and troubleshooting.

5. **Reliable Performance** MFJ is a well-known brand in amateur radio with a reputation for durable and functional accessories. The 1702CN is designed to handle standard HF power levels (up to 1.5 kW on most bands), making it suitable for most amateur radio applications.

6. **Cost-Effective Solution** Compared to manual relays or more complex switching systems, the 1702CN offers a budget-friendly way to manage multiple antennas without requiring additional hardware.

7. **No External Power Required** The switch operates passively, meaning it doesn t require batteries or external power, which simplifies deployment in portable or emergency scenarios.

1. **Limited Bandwidth** The 1702CN is designed for HF (High Frequency) bands (typically 1.8 30 MHz) and may not be suitable for VHF/UHF or digital modes (e.g., FT8, EME) that require wider bandwidth or different impedance matching.

2. **No Built-in Band Selection** Unlike some higher-end antenna switches, the 1702CN does not automatically select the best antenna for a given band. You must manually choose the correct position, which can be inconvenient during rapid band-hopping or when operating SSB/CW with frequent frequency changes.

3. **PL-259 Connectors May Be Fragile** While PL-259 connectors are standard, they can be prone to loosening or corrosion over time, especially in humid or outdoor environments. Some users may prefer more robust connectors like N-type for long-term reliability.

4. **No Remote Control or Automation** The switch lacks built-in remote control (e.g., via serial or USB), meaning you must physically rotate the switch or use an external relay system for automation, which adds complexity.

5. **Potential for Signal Loss or Reflection** Poorly matched antennas or long coax runs can introduce standing waves or signal degradation. While the 1702CN itself is low-loss, the overall system performance depends on the quality of your antennas and feedlines.

6. **Limited Current Rating** While the 1702CN handles up to 1.5 kW on most bands, it may not be suitable for high-power operations (e.g., 2 kW or above) without additional cooling or a more robust switch.

7. **No Built-in SWR Protection** Unlike some higher-end switches, the 1702CN does not include automatic SWR protection, meaning you must rely on your radio s built-in protection or an external SWR meter to prevent damage from high SWR conditions.

The **MFJ-1702CN** is a practical and affordable solution for amateur radio operators who need to manage multiple antennas without the complexity of manual relays or expensive switching systems. It excels in portable, field, or multi-band setups where simplicity and reliability are key. However, it is not ideal for advanced users requiring automation, VHF/UHF support, or high-power operations beyond its rated capacity.

For most HF operators who prioritize ease of use and cost-effectiveness, the 1702CN is a solid choice. If you need more advanced features (e.g., remote control, wider bandwidth, or higher power handling), you may want to consider alternatives like the **MFJ-993C** (a more advanced 4-position switch with remote control) or a **manual relay system** for specific applications.

---

- You operate primarily on HF bands (1.8 30 MHz).

- You need a simple, portable way to switch between 2 4 antennas.

- You are on a budget and want a reliable, no-frills solution.

- Your power levels are within the 1.5 kW limit.

- You require VHF/UHF or digital mode support.

- You need remote control or automation for your antenna switch.

- You operate at high power (above 1.5 kW) and need a more robust switch.

- You prefer N-type connectors for better durability in outdoor environments.

For most casual to intermediate HF operators, the **MFJ-1702CN is a well-rounded and cost-effective choice**. Pair it with high-quality coax and antennas to maximize performance.
