Thank you for choosing EAntenna.
All our products are manufactured and developed with the best materials on the market, to offer the best qualities and
guarantees to our customers.
The Yagi type MOXON antennas were developed by Leslie A. Moxon, to be used in communications in HF during the 2nd half
of the 20th century, quite successfully. Its cost, profit and ease of construction make it an option very convenient. As it is a
specific antenna according to the bands in which we want to operate. The address of the maximum Gain is obtained in the
opposite direction to the reflector and perpendicular to the radiating element. According to the position with respect to
ground, horizontal or vertical, will be its polarization. It is very important that this coincides with the polarization used in the
antenna of the equipment to which you connect with this antenna.
Like any antenna manufactured by EAntenna, we do not include a connector, to have the minimum losses. We include
terminals to solder directly, although we offer as an option balun or ferrites EMI / RFI.
We detail the materials used, for their best use and assembly. All the fittings are made of stainless steel and the
Aluminum is made of T6061 or T6063 alloy, known as Aeronautical Aluminium, which offers the best conditions to withstand
the most extreme climates, the force of the wind and the best conductivity. The plastics used, is Polyamide or Polypropylene,
which offer the best hardness and durability for the passage of time. We offer guarantee in the operation, and guarantee in the
ironworks, delivering the kit of hardware some extra pieces, for possible losses or forced breakages.
In the following pages we detail the exploded view with its graphics.
