High gain bets Beams

Once I heard Don Wallace W6AM and a neighbor comparing antennas on 20 meters.  Don was running one of his rhombics aimed toward Europe.  His neighbor said he was running a 5 element mono-band yagi at 150 feet (I think it was).  Anyway while I was listening they compared the two antennas getting comparative signal reports from many European stations.  Don's rhombic was almost always at least 20dB stronger than his neighbor who was running the 5 element yage at 150 feet.

I understand that theory (EZNEC) does not predict this result, but what happens on-the-air is what separates the big guns from the little pistols.

Your Go-To Source

Welcome to KOUO rhombic antenna Farm, a unique blog here for you to explore. Building installing and using large antennas has added such value to my life, and I love having the opportunity to share my passions and thoughts with my loyal readers. Read on, and enjoy.



I hope the this will serve as a useful source to those seeking inspiration on building large wire antenna, or if you need help advice on your project. I started writing about my passions, my thoughts, and curious wonderings about our world. Take some time to explore the blog, read something interesting, and feel free to reach out if you would like to collaborate on a project together. If you have had or currently have rhombic or Vee beams up please provide us all the information about your projects. Most people don't really understand how much gain can be achieved out of these antennas and modeling doesn't do them Justice. All of my antennas have had measurements using broadcast type metering equipment for E&H field in the far field



Thanks for your interest in my amateur radio station K0UO, and particularly my rhombic antennas which are some of the largest amateur radio antennas in the United States. Each one taking over six and a half acres of property. these rhombic and Vee beam antennas are optimized for 40 and above
