Do you mean the antenna with the two legs where the one leg is

That is not a correct way to feed a dipole!
There must be a balun between the coax and the dipole.

The balun only improve the monopole . The only one leg is red (radiate):

The color someone used in an illustrative diagram has no significance
in the operation of the antenna.

Both the halves of the dipole are involved in the radiation.

If it is feed by the two wires transmission line:

Did you notice there is no connection to ground required?
