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.
