Review PAR ELECTRONICS Meter End Fedz Antenna Lnr

The **PAF EF-20 20-Meter End-Fed Halfwave Antenna with 100-Foot Coaxial Cable (LNR)** is a versatile and high-performance solution designed for amateur radio operators seeking a compact yet efficient antenna system for the popular 20-meter band. This antenna combines the simplicity of an end-fed halfwave design with the reliability of a low-loss, 100-foot length of coaxial cable, making it an ideal choice for portable operations, temporary setups, or even as a secondary antenna for fixed stations where space is limited. The EF-20 is engineered to deliver excellent performance across the 20-meter band (14.000 14.350 MHz), providing broad coverage and minimal tuning requirements, which simplifies operation for both beginners and experienced hams alike. Its end-fed configuration eliminates the need for a traditional tuner or matching network in many cases, as the built-in loading coil and impedance-matching properties of the coaxial cable allow for direct connection to most transceivers without significant signal loss. The 100-foot length of LNR-400 coaxial cable not only ensures a clean, low-noise feedline but also provides flexibility in deployment, whether you're setting up in a backyard, at a field day event, or in a remote location where long runs of cable are necessary. The antenna s compact size approximately 20 feet in length makes it easy to store and transport, while its lightweight construction ensures durability in various environmental conditions. Whether you're a DX enthusiast chasing long-distance contacts, a contest participant looking for reliable performance under pressure, or a casual operator enjoying the simplicity of a single-band antenna, the PAF EF-20 offers a balanced blend of ease of use and performance that makes it a standout choice in the world of portable and temporary antenna solutions.

### Pros and Cons of buying a Par EF-20 20-Meter End-Fed Half-Wave Antenna with LNR

1. **Simplicity and Ease of Installation** The EF-20 is a straightforward end-fed half-wave antenna designed for the 20-meter band. It requires minimal setup, as it does not need a ground system or a tuner for basic operation (though a tuner is recommended for optimal performance). This makes it ideal for portable or temporary installations, such as field day or emergency setups.

2. **Portability** The antenna is lightweight and can be easily transported. It comes with a built-in counterpoise (the LNR, or "Long Neutralizer Rod"), which helps reduce RF feedback and allows it to be used without a tuner in some cases. This makes it suitable for mobile or travel use, such as in a car or RV.

3. **No Tuner Required for Basic Use** Unlike many end-fed antennas, the EF-20 can be used without a tuner on the 20-meter band, as it is designed to present a reasonable impedance (typically around 300 400 ohms) when properly terminated with the included LNR. This simplifies the rigging process, especially for beginners or those without a tuner.

4. **Good Performance on 20 Meters** The 20-meter band is one of the most popular HF bands for amateur radio, with strong worldwide propagation. The EF-20 is well-suited for this band, offering decent gain and reasonable efficiency when properly fed. It can also be used on other bands with the help of a tuner, though performance may vary.

5. **Durability and Weather Resistance** The antenna is constructed with materials that can withstand outdoor conditions, including UV resistance and corrosion protection. This makes it suitable for permanent installations as well as temporary setups.

6. **Affordability** Compared to more complex antennas like dipoles or verticals, the EF-20 is relatively inexpensive. This makes it an attractive option for budget-conscious operators who still want a functional antenna.

7. **No Ground System Needed** Unlike ground-mounted antennas (e.g., verticals), the EF-20 does not require a radial system or ground rods. This reduces installation complexity and eliminates the need for ground considerations.

8. **Versatility** While primarily designed for 20 meters, the EF-20 can be used on other HF bands (e.g., 15, 10 meters) with the addition of a tuner. This flexibility allows operators to adapt the antenna to different operating conditions.

1. **Limited Bandwidth Without a Tuner** The EF-20 is optimized for the 20-meter band and may not perform well on other bands without a tuner. Even on 20 meters, its bandwidth is narrower than a full-size dipole, meaning you may struggle to cover the entire band without a tuner or matching network.

2. **Impedance Mismatch** The antenna presents a high impedance (typically 300 400 ohms) when fed directly with the LNR. This requires a balun or matching device to interface with most transceivers, which may not be included. Some radios may not handle this impedance well without proper matching, leading to poor efficiency or SWR issues.

3. **Potential for RF Feedback** End-fed antennas can be prone to RF feedback, especially if not properly terminated or if the feed line is too long or improperly routed. The LNR helps mitigate this, but it is not foolproof. Operators may still experience feedback or "birdies" in their receivers if the setup is not optimized.

4. **Lower Gain Compared to Dipoles** A properly installed dipole typically offers higher gain and better radiation efficiency than an end-fed antenna. The EF-20 is not as efficient as a dipole, which may result in weaker signals, especially in weak-signal conditions or during poor propagation.

5. **Dependence on Feed Line Length** The performance of the EF-20 is sensitive to the length of the feed line. If the feed line is too long or improperly terminated, it can affect the antenna s impedance and tuning. This requires careful planning during installation to ensure optimal performance.

6. **Limited Height Flexibility** The antenna is designed for a specific length (half-wave on 20 meters, 31 feet or 9.45 meters). If installed at a height significantly different from its design length, its performance may degrade. Unlike a dipole, which can be adjusted for height, the EF-20 is fixed in length.

7. **Potential for Wind Damage** While the antenna is durable, long wire antennas like the EF-20 can be susceptible to wind damage, especially if not properly secured or if the supporting structure is weak. This is a risk for any outdoor antenna installation.

8. **Noisy Operation in Some Cases** Due to its design, the EF-20 can sometimes introduce noise or interference into the receiver, particularly if the feed line is not properly shielded or if the antenna is too close to the radio. This is more common in portable setups where the feed line is not well-managed.

9. **Limited Use on Lower Bands** While the EF-20 can theoretically be used on lower bands (e.g., 40 meters) with a tuner, its performance will be poor due to its length. The antenna becomes electrically short on these bands, resulting in very low radiation efficiency.

10. **Learning Curve for Optimal Setup** Achieving the best performance from the EF-20 requires understanding how to properly terminate it with the LNR, manage the feed line, and possibly use a tuner. Beginners may struggle with these aspects, leading to suboptimal results.

The Par EF-20 20-meter end-fed antenna with LNR is a practical and affordable option for amateur radio operators who prioritize simplicity, portability, and ease of installation. It excels in scenarios where a permanent or complex antenna setup is not feasible, such as field operations, emergency communications, or mobile use. Its lack of requirement for a tuner (on 20 meters) and minimal installation needs make it an attractive choice for beginners or operators with limited space.

However, its limitations such as narrow bandwidth, lower gain compared to dipoles, and potential RF feedback issues mean it is not the best choice for serious DXers or those seeking optimal performance on multiple bands. For operators who primarily use the 20-meter band and value simplicity over maximum efficiency, the EF-20 is a solid, no-frills antenna. For those who demand better performance, especially on multiple bands, a dipole, vertical, or more advanced antenna system may be preferable.

---

- You need a simple, portable, or temporary antenna for 20-meter operations.

- You do not have space for a full-size dipole or vertical antenna.

- You are on a budget and want a low-cost solution for basic HF communication.

- You plan to use it primarily for local or regional contacts rather than long-distance DX.

- You require optimal performance on multiple bands or for weak-signal work.

- You do not have a tuner or balun to properly match the antenna to your radio.

- You prioritize maximum gain and efficiency over simplicity.

- You plan to use it for serious DXing or contesting, where a dipole or vertical would be more effective.

For most casual operators or those needing a backup antenna, the EF-20 is a worthwhile purchase. However, if you are serious about amateur radio and want the best possible performance, investing in a properly installed dipole or vertical antenna system would be a better long-term solution.
