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.

- Page 3 ESPAÑOL Para montar el BOOM, tiene que hacer coincidir telescopicamente las partes de boom que tienen la misma letra ( p.ej: A-A, B-B, C-C etc), y una vez hecho, se van fijando con los tornillos DIN 933 M6X16 y arandela DIN 9021 M6. Se recomienda poner todas los torni- llos y arandelas antes de fijarla a tope para no dañar ninguna rosca del BOOM.
- Page 4 ESPAÑOL El primer paso de ensamblaje de los elementos es colocar en orden por diámetros según la pagina 2. Una vez hecho esto tener en cuenta que en cada extremo de los elementos hay una parte de cada tubo que tiene los agujeros mar gruesos. Estos son los que van en el extremo hacia el extremo de la antena, ya que los agujeros anchos son donde entra la cabeza del tornillo DIN 7984 y presiona al tubo interior.
- Page 5 ENGLISH The first step of assembling the elements is to place in order by diameters according to page 2. Once this is done keep in mind that at each end of the elements there is a part of each tube that has thick sea holes. These are the ones that go at the end towards the end of the antenna, since the wide holes are where the head of the DIN 7984 screw enters.

Los 4 agujeros de mayor grosor tienen la función de que hagan la mayor fuerza sobre el mástil, mediante abarcones redondos de M8. Los abarcones redondos de M8 (A-0163), van fijados mediante arandela DIN 9021 M8 y tuerca DIN 934 M8 proporcionadas en el mismo abarcón, y fijada al mástil con la Mordaza (23035.50).
- Page 7 MAST TO BOOM PLATE ASSEMBLY ENGLISH The clamping plate BOOM / MAST (EA010010) 250X200X10mm consists of 12 holes; 4 thick for round U-bolts and 8 small holes to joint the (EA010276) securing the BOOM. The 4 holes are thicker function that make the greatest force on the mast by means of M8 round U-bolts. Round U-bolts M8 (A-0163), are secured by washer DIN 9021 M8 and nut DIN 934 M8 provided in the same U-bolt, and fixed to the mast with clamp (23035.50).
