Entry Page
The first page we see acts as the entry point to both the Pt-Pt Link and Area Broadcast calculations. The initial location of the transmitter needs to be entered in one of the different formats given.
Direct entry of the latitude and longitude in either decimal or the classical degrees, minutes and seconds.
As a location on the globe. Choose a continent, then country, then city. The UK has a specific entry. The map around the choosen point displayed. By using the tabs the map can be moved north, south, east, west and changed in size. Likewise the map can be flipped between geographic and terrain. Thus a suitable high point can be found for the broadcast transmitter.
Having settled on the Tx location, examined the terrain around the site we can continue to enter the Tx parameters. Note: the broadcast analysis will be at a radius that covers the shown map.
It needs to be noted that all non-UK maps, both geographic and terrain are latitude longitide linear. That is the distance span will vary with latitude and longitude. Thus a constant distance radius of a point will describe an ellipse. Hover the UK maps based upon the Ordenace Survey series the maps are distance linear and constant distance coverage will describe a circle.
