Where would I attach radials on a dipole? Hi Bob, Not to the dipole certainly; to the ground below the dipole. It is, after all, the ground that presents the loss. The radials reduce that loss as is their function. For example, a 20M dipole one halfwave over a ground mat (1M grid about 1 wavelength in XY dimension), shows a gain of 7dBi at 30°. Take away that ground mat, it shows a gain of 6.5dBi at that same 30°. Nothing remarkable in my book, but I have the ground mat anyway. 73's Richard Clark, KB7QHC |
