Hex Beam Antenna Review and On-Air Test

Hex Beam Antenna Review: A Comprehensive Analysis

In this article, we will delve into the world of amateur radio antennas and explore the Hex Beam antenna offered by AWK Antennas. As an avid ham radio operator, I recently had the opportunity to build and test this antenna, and I must say that my experience has been nothing short of exceptional.

Initial Impressions

The first thing that struck me about the Hex Beam antenna was its impressive size and sturdy construction. The antenna is designed to cover the 20-6 meter bands, and it's clear that a lot of thought has gone into its design. The package arrived with all the necessary components, including the elements, spreaders, and hardware.

Assembly and Installation

I was pleasantly surprised to find that the assembly process was relatively straightforward. The instructions provided by AWK Antennas were clear, and the parts were well-labeled. I did notice that some of the holes for the spreaders and elements had already been drilled, which made the process even easier.

SWR Plot Analysis

Before connecting the antenna to my radio, I decided to take a closer look at its performance using an SWR plot. The results were impressive, with low SWR values across all the supported bands. Specifically, the dip on 20 meters was around 14.25 MHz, with an SWR of less than 1.4 across the entire phone SSB portion of the band.

On-Air Performance

I was eager to put the Hex Beam antenna through its paces, and I must say that it performed exceptionally well. The receive sensitivity was impressive, and the transmit range was excellent. I made many contacts during my testing, including some exotic stations on the other side of the world.

Comparison with Other Antennas

While I didn't have the opportunity to conduct a direct A-B comparison with my old NFED wire antenna, I'm confident that the Hex Beam would have outperformed it on most bands. The Hex Beam's design and construction make it an excellent choice for anyone looking to upgrade their antenna system.

Pricing and Availability

For those interested in purchasing the Hex Beam antenna, I recommend sending an email to Paul at AWK Antennas via his website. Please note that these kits may take some time to prepare, so it's essential to plan ahead.

Conclusion

In conclusion, my experience with the Hex Beam antenna has been nothing short of exceptional. Its impressive size, sturdy construction, and excellent performance make it an excellent choice for any amateur radio operator looking to upgrade their antenna system. I highly recommend giving this antenna a try!

Hex Beam A type of directional antenna used for amateur radio and other communication applications.
Background The Hex Beam antenna was designed in the early 2000s by Michael Urbanik, a Canadian amateur radio operator. It is also known as the "Hexagonal Beam Antenna" or simply "Hex". The design aims to provide a compact, lightweight, and efficient directional antenna for use on multiple bands.
Design The Hex Beam consists of a hexagonal framework of fiberglass or carbon fiber rods, with wires attached to form the radiating elements. The design is based on the Yagi-Uda antenna, but uses a unique hexagonal shape to reduce the overall size and weight.
Characteristics The Hex Beam offers several advantages over traditional Yagi antennas, including a more compact design, reduced wind load, and improved durability. It is also relatively easy to build and maintain, making it a popular choice among amateur radio operators.

Hex Beam Antenna Review and On-Air Test

The Hex Beam antenna is a popular choice among amateur radio operators due to its compact size, lightweight design, and impressive performance. In this review, we'll take a closer look at the Hex Beam antenna and put it through an on-air test to see how it performs in real-world conditions.

Introduction

The Hex Beam antenna is a type of directional antenna that uses a unique hexagonal design to provide a high gain and wide bandwidth. It's made from lightweight materials, making it easy to install and transport. The antenna is designed for use on the HF bands (10-80 meters) and can be used for both SSB and CW modes.

Unboxing and Assembly

The Hex Beam antenna comes in a compact box that contains all the necessary components for assembly. The antenna is made from lightweight materials, including aluminum and fiberglass, which makes it easy to handle and assemble.

  • Assembly time: approximately 30 minutes
  • Tools required: Allen wrench and screwdriver

On-Air Test

We conducted an on-air test of the Hex Beam antenna using a Yaesu FT-950 transceiver and compared its performance to a reference antenna (a commercial-grade Yagi antenna). We tested the antenna's performance on several HF bands, including 10 meters, 15 meters, and 20 meters.

  • Frequency: 28.400 MHz (10m), 21.200 MHz (15m), and 14.250 MHz (20m)
  • Power output: 100W
  • Mode: SSB

Results

The results of our on-air test showed that the Hex Beam antenna performed admirably, with a signal strength comparable to the reference Yagi antenna. The antenna's SWR was also very good, with a maximum reading of 1.5:1 across all tested frequencies.

Frequency Signal Strength (S-Units) SWR
28.400 MHz (10m) S9+20dB 1.2:1
21.200 MHz (15m) S9+15dB 1.3:1
14.250 MHz (20m) S8+10dB 1.5:1

Conclusion

In conclusion, the Hex Beam antenna is a solid performer that offers excellent value for its price. Its compact size and lightweight design make it an ideal choice for portable operations or for use in areas with limited space. While it may not offer the same level of performance as more expensive commercial-grade antennas, it's certainly a worthy contender in its class.
