The D4 VHF antenna represents - four loop vibrators Pistolcorsa D1 VHF + one adder TK-54V. Its main advantages are wide bandwidth and relatively low sensitivity to interference of industrial origin.
Prefabricated design allows easy installation and dismantling of the antenna, and welded dipole eliminates the occurrence of intermodulation. By changing the distance from the radiating element to the mast, it is possible to correct its directional pattern within small limits.
The antenna has a reliable polymer coating that protects against aggressive environments and icing. All-metal construction provides reliable lightning protection.
