Specifications 144LFA4

  • 30x2mm square boom. Available for both FM and SSB, as the mast plate is behind the elements, thus eliminating the mast interactions with the elements.
  • Elements of 10mm in diameter, except that the LOOP is 13mm and 10mm at the ends.
  • Mast plate of 100x100mm with 6mm thick with U-bolts M6, available for masts up to 55mm. in diameter.

Characteristics of the 144LFA4

  • With this antenna may realize that with only 4 items can get results with little antennas of this size can be made. This antenna has a provision to ensure that only 2 or 4 antennas enfasadas improve long boom lengths.
  • Simple and quick, because the boom of the antenna is delivered in one piece.
  • Antenna very light weight but very robust.
  • Enfasar Available for 2 or more units in a short (under table include enfasamiento) with our Power Splitter.
  • 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)
