Specifications 50LFA4

  • 30x2mm square boom.
  • Items divided into 2 sections; central 13mm diameter and 10mm tips, except that the LOOP is 6mm.
  • Mast plate of 100x100mm 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 50LFA4

  • It is certainly one of the antennas sold, not only for its design, but with only 4 meter boom, you get very good results.
  • A lobe extremely wide, makes this antenna ideal IS in summer, and as daily Tropo not for other types of propagation in this band as PET, MS and F2, among others.
  • 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)
