?If I am understanding your query correc, then the aerial design was known as a Moxon arial

A Moxon antenna is?a type of directional antenna, often referred to as a "Moxon rectangle," which is a simple, two-element parasitic array design with a rectangular shape, where the ends of the elements are bent towards each other, creating a compact antenna with good gain and a high front-to-back ratio, making it popular among amateur radio enthusiasts due to its ease of construction and performance in limited space situations;?it was developed by Les Moxon (G6XN).?
Key points about Moxon antennas:
  • Design:?It consists of a driven element (radiator) and a reflector element, both bent inwards to form a rectangular shape.?
  • Advantages:?Compared to a standard Yagi antenna, a Moxon antenna offers similar gain while being significantly smaller and having a much better front-to-back ratio.?
Hope this?is helpful

Norman.

I use a homemade 3 element Yagi, based on Paul Hyde's one from 'Sky at Night' magazine in 2014 and currently available on the BAA website via:

What are the different types of aerials recommended for 143Mhz meteor scatter? I would like a list to add to my talk. I use a Moxon but I know there are other types
