3D Radio Wave Transmission Illustration - Part II

Job ID: 40623798

Budget: $10 – $100 USD

I am looking to hire an illustrator with a technical background who can proficiently depict a radio wave transmission in a technical book about "radio broadcasts" and "mobile phones". This illustration should help explain and visualize how radio wave transmission works.

I have attached some drawings I use to explain how radio broadcast covers an area. This is true for radio and also mobile towers. The circle shows the area a radio station covers.

The reality is that a radio creates a "sphere" around itself. A mobile phone tower or radio tower makes a sphere around itself. If you are 10 KM away from the tower, you are inside the sphere. If you are 10 KM above the sphere you are also inside the sphere. I want a clean drawing like is shown in the attachment 3D tower.

Notice that when the tower has a sphere, part of the sphere goes under the ground. At ground level is a big circle where the sphere and the ground meet.

Please help me and make this drawing. I understand it is a little confusing. I will pay for the best two results. Thank you.
