Antennas for Links
General. The LOG 1.8G R and LOG 2.7G R Directional Antennas are designed for short distance FM Radio & TV microwave links purposes in 1.6 – 1.8 GHz (LOG 1.8G R) and 1.8 – 2.7 GHz (LOG 2.7G R) frequency ranges. These antennas are made with non-corrosive aluminium alloy and composed of 27 elements, one polyester radome and a mounting bracket.
Horizontal or Vertical polarization are possible with the standard mounting brackets.
Water, icing and moisture protection. The internal elements are protected against water, icing and moisture ingress by a sealed polyester radome.
Instant installation. The reduced overall dimensions and the low weight permit an easy installation even on light poles.
Lightning resistance is guaranteed by the DC ground potential of the entire antenna.
