What if the chokes and cell are like an antenna with tuned coil?
This picture is a representation of the 1/4 wave ground plane antenna looking like a round dough nut as the radiating wave form and the antenna is pushed up through the middle,
This radiating pattern all round the antenna is what is meant by OMNI-DIRECTIONAL.
5/8 waves or 1/4 waves are the common ones....
With a properly tuned aerial on the end of the coax, the electrical energy, or to use the correct term, the Radio Frequency Signal (RF signal), will now radiate into the atmosphere.
