Please make sure that you don't mind before purchasing. The standing waves of each section of the antenna will differ depending on the place where it is erected.
Application: The 20-meter band of this antenna is a standard quarter wavelength natural resonance. Find a place with fertile soil to mount the antenna, and insert the ground pins in places with high conductivity such as water, lake and seaside. There are four counterpoises, each with 16 small ones and 64 counterpoises in total, with a doubled efficiency.
But if the soil is poor, the effect will be reduced. The 40-meter band antenna uses a load coil, which is definitely slightly less efficient than a standard quarter wavelength antenna. The antenna bandwidth is very large, and has been praised by many enthusiasts. Usually it costs about 30USD-50USD.
