Ensys Moxon 402MHz Directional Antenna

Description

A 3D Printed Frame Moxon Antenna With SMA connector.
Moxon directional antenna made with 3D printed frame and fiberglass tube. It is quite sturdy and rigid.
Each antenna is SWR tested and should be be below SWR <1.2 for the rated frequency. It can reach almost
SWR 1.0  at +- 10MHz of the rated frequency.
The Moxon is a directional antenna system that is gaining in popularity because it offers three very distinct advantages over a typical two element Yagi:
Small in physical size
. The Moxon can be built using a very lightweight structure and wire elements, which will fit into a footprint about two thirds the area required for a conventional beam.  You can see by the measurements above that a 20 meter Moxon is only 25 by 9 feet.  Being a very light structure, typically made from wire and lightweight spreaders, it can easily be mast mounted on a lightweight pole, hoisted up in a tree from an overhanging branch, or turned vertically and ground mounted!  As such it also makes an excellent field antenna.
Outstanding front to back ratio.
The Moxon’s front-to-back ratio models at greater than 30dB! Moreover, close-gap coupling enables the Moxon’s enhanced performance to be realized at lower elevation heights of only 1/2 wavelength.  As seen below, the Moxon exhibits a broad forward area combined with superior front to back.
The Moxon is a
50 ohm antenna
,
generating a near perfect 1:1 swr without requiring any additional matching devices. It is also quite broadbanded allowing for effective full band coverage.
