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 LFA antennas have an input impedance of 50 Ohm in the antenna, so no coupling is necessary. The loop is at the same time a coupling
system and director element and this presents many advantages when modeling.
The 'real' impedance of each LFA varies greatly. But, the impedance presented at the antenna entry point is always 50 Ohm. Therefore, there
is no limitation on the results of any optimization tool achieved with a single input impedance, but it manages to change the width and length of
the loop keeping the impedance at 50 Ohm. This feature is very important to ensure good performance, bandwidth and low SWR in the
antenna.
This additional flexibility also allows more lateral lobes to be suppressed and a better front-to-back (F / B) ratio compared to traditional Yagis.
With time it is possible to achieve an excellent balance between design, F/B, gain and bandwidth.
Additionally, the proximity of the loop and the antenna entry point make the LFA less susceptible to noise and static nearby. In addition, the low
level of the LFA lateral lobes provides a winning formula for an antenna with super low noise!
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 Duralumin that offers the best conditions to be weatherproof, the force of the wind and the best conductivity. The
plastics used, are Polyamide and offer the best hardness and durability for years and years.
We offer warranty on operation, and warranty on hardware, delivering the hardware kit with some additional pieces for possible losses or
forced breaks. In addition, we offer Allen keys and fixed mounting elements.
In the following pages you can see detailed graphics of the parts.

  • Página 4 Cara C y D; en estos agujeros van introducidos los elementos. El montaje de EAntenna es tan facil como introducir cada elemento en su correspondiente agujero en el boom (Cara C y D), y con el el tornillo DIN 7991 M4x25 roscar sobre el mismo elemento (CARA A). Para reforzar el elemento al boom, se añade una tuerca M4 DIN 934 que con una llave de vaso o tubo del número 7 se aprieta facilmente (CARA B)
  • Página 5 ENGLISH Adjusting SWR: Once positioned the antenna with your measurements, you may need some fine-tuning to get the SWR desired. Shifting the curve piece inward or outward several millimeters, is the way to go. Looking to the center frequency is 144,300 MHz in the lower SWR.
