Omnidirectional E1 antennas and vertically stacked arrays E1 type.

Each element of vertical array is a low-gain omnidirectional antenna of enforced construction. Frequency range can be specified by customer. As an example, an aviation band 118-136 MHz antenna E1/118-136 is presented. Antennas of this band are made of 40x40x3 mm aluminum sections to withstand the strongest ice and wind (up to 55 m/s) conditions. Antennas are powder painted (color can be specified by customer).

* depends on mounting

Strong mounting clamp is made of hot-galvanized steel. It is of special construction making it possible to move along the mounting side of antenna. As an option additional clamp can be ordered. So antenna can be fixed in two points on any mast with different lattice widths and leg diameters.

High-gain multi-antenna arrays come with all necessary power dividers and connecting cables. The system on the top picture is a high-gain 8-antenna vertical array 8×1×E1/118-136 for aviation band 118-136 MHz.
