Antenna D1 VHF represents folded Pistolcors dipole. Its main advantages are wide band and relatively low susceptibility to technical born interference. Collapsible construction allows easy antenna mounting and dismounting, and welded dipole eliminates intermodulation. Emitting unit directional pattern can be slightly corrected by changing distance from it to mast. Antenna has reliable polymeric coating, which protects from hostile environment and icing. All-metal construction provides reliable lightning protection.
