Antenna D1 ALT represents folded Pistolcors dipole. It can be used in Altay and Volemfrom systems, river craft radio communication and for telemetry. Collapsible construction enables easy antenna mounting and dismounting. Emitting unit directional pattern can be slightly corrected by changing distance from it to mast. All-welded dipole design eliminates possibility of intermodulation. Antenna has reliable polymeric coating, which protects from hostile environment and icing. All-metal structure provides reliable lightning protection.
D2 ALT, D4 ALT and D8 ALT antennas are built along parallel addition of two, four and eight collinear arranged active folded dipole powers principle.
