Product Information
  • Overview
  • Description
Dimensions 186x10x10cm, Weight 3.85kg  

The antennas for VHF EAntenna LFA represent the largest development in antennas with moderate boom length for a single performance.

This performance is characterized in that:

  •  You can listen to very low signals without QRM and QRN noise alters the audio clarity.
  •  Direct feeding is 50 ohms, which does not have any loss with respect to lines of adaptation.
  •  The bandwidth covers the entire band with low SWR.
  •  The radiation lobe is wide, so that the signal is not as selective as you turn the minimum antenna.
  •  It’s ratio of F / B is high, since only antenna boom lengths can get exaggerated.
  •  The gain is comparable with other models of antennas always larger in dimensions.
Specifications 144LFA5
  •  30x2mm square boom. With 2 versions, FM and SSB, to put it in horitonzal polarization with power central mast, or vertical polarization, we recommend taking the reflector behind the antenna to eliminate interactions with the mast.
  •  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 144LFA5

  •  This antenna is designed for a very acceptable performance in both vertical and horizontal polarization.
  •  Simple and quick, because the boom of the antenna is delivered in one piece.
  •  Antenna very light weight but very robust.
  •  Stack Available for 2 or more units in a short (under stack distance table include) with our Power Splitter.
