Yes, that would be true if there were helicopters that could fly 10 miles above ground!
The transmitted waves are not like a string tieing the antennas together, they are more like the light from a light bulb, they travel outwards from the source and gradually get weaker in strength as they spread out over a wider area. Any antenna within the signal area will pick up some of the signal and the closer to the transmitter, the stronger it will be.
Note that another factor becomes involved, called 'directivity', this is a measure of how well an antenna can concentrate it's signal in one direction. Obviously, if you use a highly directive antenna to transmit, it means the signal will be stronger in that direction but weaker in other directions. Most TV stations for example use 'omni-directional' antennas to transmit so their signal reaches the widest possible area but individual houses use directional antennas pointing to it to pick up the strongest possible signal and to exclude interference from other directions.
I used to explain this to students like this:
Think of a rope, say 2 metres (about 6') long tied in a loop. The length represents the power of the transmitter, longer means more power.
Lie it on the ground in a circle and place a stake in the middle of the circle. The stake represents the transmitter antenna.
The rope marks the range the transmission can reach, equal in all directions from the center.
Keeping the circle, pull the rope to one side and you will see the range decreases at one side but increases in the opposite angle.
Keep pulling the rope aside until it hooks around the stake, now there is almost no range on the side touching the stake but much longer range the other way.
Pull even harder, now the circle deforms into an ellipse and eventually it tightly doubles back on itself. The range in the direction you pulled is maxed out.
The outline of the rope represents the directivity of the antenna, the narrower the beam, the further it reaches.
In a real antenna, all this happens in 3D, you have to imagine the rope outline on the ground has height as well as length and width.
