A magnetic loop will work indoor and outdoor. Low on the ground and high
in
the sky. And without a counterpoise. Dipoles require space. Verticals
require counterpoise. When there is little space or other restrictions the
loop is a nice alternative.

Your loop is not magnetic. Look at Fig. 2:

Radio wavesare are radiated from the nodes. In dipole the nodes are created
by reflected wave (waves in the opposite direction). In the loop the waves
travel in oppsite direction and create the nodes also.

Verticals work like the Kundt's tube. Dipoles like the two Kundt's tubes.
A loop is like a dipole where the reflected wave is replacesd by the on from
the second wire.

Hertz has the dipole and the loop:
