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.

Just remove the bias plys and substitute the radials! 8^)

But seriously, they are set the same way as you would on a vertical, in
the ground. And Richard is right.
