Hi, it is my webpage:

http://www.covermap.es

Covermap is an application that allows the calculation of propagation
loss of a particular antenna defined by the user.
In covermap you have the ability to see the extension of the radio
antenna (coverage mode), the different coverage cells of positioned
antennas (cellular mode) and get the loss in decibels on a particular
point with respect to the antenna (point to point mode).
