RadioPlanner 2.1 update 190919

1. A new type of project has been added - Air-to-Ground Communication.

Now you can perform the calculation of coverage for air-to-ground and radionavigation systems operating in the VHF, UHF and microwave frequency bands.

Area studies for air-to-ground communication systems:

- Received power Air-to-Ground link;

- Received power Ground-to-Air link;

- Strongest (most likely) Server Air-to-Ground link.

The propagation model is a hybrid model based upon the recommendation ITU-R P.528-3 (02/2012) "Propagation curves for aeronautical mobile and radionavigation services using the VHF, UHF and SHF bands" and the recommendation ITU-R P. 526-14 "Propagation by Diffraction".

2. Added FCC contours calculation for broadcast transmitters.

See the updated user manual for details.
