Specifications 50LFA5S

  • 30x2mm square boom.
  • Items divided into 2 sections; central 13mm diameter and 10mm tips, except that the LOOP is 8mm.
  • Mast plate of 150x100mm with 6mm thick with square U-bolts M6 fuck boom to the plate and U-bolts of M8 to the plate to the mast.

Characteristics of the 50LFA5S

  • The best 5-element antenna with these dimensions. Adjusting the maximum gain and F / B with respect to a narrow bandwidth, we have a gain never imagined in a boom so small.
    Only 3.95 m makes this antenna boom that enters their necesitades better with respect to size.
  • With a very wide as the lobe of this antenna, you can begin to achieve remarkable results in this band.
  • Simple and quick, because the boom joints are easy to assemble. And the elements are attached by clamps Without End (Hose Clamp) for quick installation and durable fastening.
  • Antenna very solid construction, and with a weight very acceptable.
  • Available for 2 or 4 units enfasar in a short (under enfasamiento table included), and to make a profit no big antenna can get.
  • The food is straightforward to 50 Ohms, which has not lost any respect to lines of adaptation. (You can request an optional cable terminated with connector and soldered PL-UHF, N or BNC on the end if required)

V = 4.95 to 5.78 m (5.50 m optimal)

Calculation of 2 antennas:

@ Vx2 5.50 m Gain: 13.76 dBi @ 50.150 MHz

@ Vx2 5.50 m F / B: 24.02 dB @ 50.150 MHz

At each antenna, find a serial number and / or lot located in the boom and on the outside of the box to verify that it is EAntenna bought and mounted.
A brand inspired by and for amateur radio, considering that this is a hobby.
