Log Periodic Antennas
LPD FM Series

Rev : 01 | Rev date : 29 Mar 2021

The LPD FM series log periodic antenna is a directional wideband antenna, with low VSWR and without lateral lobes. It can be used in vertical or horizontal polarization due to its rear fixation. The antenna can be used between 84 and 120MHz.


  • Receiving FM emissions in re-emission stations
  • Directive emissions
  • High 8 dBi gain, array possible
  • Multi-assembly possible
  • Easy to implement due to its low weight
  • Easily transportable as the rods can be dismantled
  • Individual packaging: 0.20 x 0.20 x 3.00m
  • All the metallic parts of the antenna are connected to the ground, helping static load out-flow.
