A Moxon Rectangle (Yagi) for 27MHz -

The Moxon Rectangle was first introduced by Les Moxon, G6XN during the 1950's. Since then it has been a very popular limited space Yagi do to its very compact size. 

The Moxon Rectangle comprises of 2 elements, a driven element and a reflector element. The tips of each element are bent towards the other with the ga being filled by an insulator to help support the ends of both elements. This results in a rectangluar shaped antenna with directional properties and very good F/B ratio.

G0KSC has taken the original design and applied modern computer optimisation techniques to talior performance to suit specific bands (these are not simply scaled from one band to another) whcih results in exceptional, band-specific performance.

 

Marine Construction - Built to last

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of 1mm) to measure the elements during production to ensure they are within 1mm of what they should be, this ensures performance is delivered.

  • Marine grade Stainless Steel Fittings
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
  • Liquid Rubber sealant provided with this antenna to perfectly seal every joint before installation

''The Yagi-antenna is very good performance.

I did tuning very careful;

SWR=1.0 with short (30cm) test cable including 2 turns choke balun. SWR=1.1 with 20m actual cable including the balun.

Thank you very much for your support and provided good antennas. JSAF is very happy and expecting good antenna network (100nm reception so far)

I will report you later more detail performance.

Have a nice days!

Specification

This antenna is made with tapered element sections starting at 3/4'' tube and finishing at 1/2'' tube. It also has fully insulated elements which will ensure continuous, high performance and ensures corrosion will not impact performance. Marine grade stainless steel is used throughout. M4 terminal coaxial termination is provided on this antenna along with a UV resistant Rubber paint (including applicator) in order to ensure all open connections can be thoroughly sealed before final installation. The boom is 1.25'' inch square 16SWG aluminium to ensure strength and rigidity and has a safe wind speed handling of well over 100MPH.

No figures are made up here as they are in some Ham Radio adverts, all performance figures are verified in the very latest software simulation packages with some antennas being professionally confirmed on an antenna range.

Manufactured the right way, not the cheapest way!
