Specifications 144LFA13

  • 35x2mm square boom.
  • Elements of 8mm in diameter, except that the LOOP is 13mm and 10mm at the ends.
  • 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 144LFA13

  • Indeed, with only 8 meters of boom, the 144LFA13 is an antenna that no other manufacturer can offer this gain.
    Ideal for DX and EME elevation, with which you can understand why a EAntenna marks the difference from other manufacturers.
  • A lobe of 30.4 Azimuth Beamwidth at -3 dB, indicates how great this antenna, have a wide radius of RX in this length of boom. Making the LFA, the dream of DXman at 144 MHz with moderate-sized antennas.
  • Simple and quick, because the boom joints are easy to assemble.
  • 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 = 2.6 to 3.8 m (optimal 3.36 m)

H = 2.6 to 4.0 m (optimum 3.5 m)

 

Calculation of 2 antennas:

Vx2@3.36 m Gain: 18.91 MHz dBi@144.300

Vx2@3.9 m Gain: 19.09 MHz dBi@144.300

Vx2@3.36 m F / B: 38.28 MHz dB@144.300

Vx2@3.9 m F / B: 40.10 MHz dB@144.300

HX2@3.5 m Gain: 18.87 MHz dBi@144.300

HX2@4.0 m Gain: 19.05 MHz dBi@144.300

HX2@3.5 m F / B: 46.48 MHz dB@144.300

HX2@4.0 m F / B: 41.44 MHz dB@144.300

 

Calculating antennas 4 H:

HX2 (4.0 m) + Vx2 (3.9 m): 22.06 MHz dBi@144.300

HX2 (3.3 m) + Vx2 (3.2 m): 21.67 MHz dBi@144.300
