Antenna D1 UHF represents folded Pistolcors dipole. Its primaries: wide operating band and nearly circular pattern. Welded construction of dipole eliminates possibility of intermodulation. Emitting unit directional pattern can be slightly corrected by changing distance from it to mast. Collapsible construction provides easy antenna mounting and dismounting. Antenna has reliable polymeric coating, which protects from hostile environment and icing.
D2, D4, and D8 antennas are built along parallel addition of two, four and eight collinear arranged active folded dipole powers principle.
