Monoband Yagi are really big antennas.
  We produce them on preliminary coordination with the customer.
  All monoband antennas are heavy duty class and can resist weather impacts.
  We offer antennas with 2, 3, 4, 5, 6, 7 and 8 elements, and boom length from 0.25 to 1.25 wavelengths. All antennas can be optimized into stack.
  There are basic antenna models shown in the tables. Each of them may be modified at customer's option.
  Antennas with long booms have truss guys which give additional construction strength.
  Most antennas have feed impedance approaching 50 Ω. The cable is connected to driven element via balun.
