DJIs biggest drone is over 1m wide and can carry a 6 kg payload.

If you could make a suitable receiver that weighed 6 kg or even 600kg, you could just suspend it from motorized plastic cables on space frame towers. Drones aren't going to make it cheaper or easier.

I suspect you could make the receivers weigh single digit grams, depending on the band.
