What are the frequencies of the bottom radials?
What is being referred to as “radials” are the radiating (or center) elements. In a discone antenna, the horizontal elements are connected to the shield and the cone is connected to the coax center conductor. The actual configuration is an upside down half-bow-tie. It is the width of the cone ( vs. the cone’s length ) that gives this antenna its broad band performance (the discone is 30 – 1300 MHz; the vertical whip is resonant in the 10M ham and 11M CB bands, for total 25 – 1300 MHz performance).
