Coverage Pattern Studies

Krohe Electronics can provide three separate types of coverage prediction studies, FCC field strength method, Drive studies, and Longley-Rice studies. Below are examples of each type in more detail.

FCC field strength study:

This method follows the FCC prescribed method of taking spot readings from 10 miles out to the loss of grade B signal on a minimum of eight radials. Below is a typical study for KMCI in Lawrence KS. This map shows both an FCC study overlayed on a drive study. Also shown is a map with the manual measurement points for the FCC study.

Drive Study:

Krohe Electronics can also provide a drive type field strength study where data is taken by literally driving a grid pattern over the entire coverage area. This method has the advantage of showing terrain shading not usually visible in the traditional FCC method. Below are two maps, one showing a typical drive study for the Topeka area. The other map shows the drive track.

Longley-Rice Study:

Krohe Electronics can provide a Longley-Rice coverage map for a specific transmitter site or sites. This study need not be limited to a TV or FM broadcast signals. Krohe Electronics can provide this service for ENG systems also which will show graphically where a live truck will work. News departments typically use this to plan live coverage of events. Please click on the maps for a larger view of a typical study. Plese see ENG truck coverage link to see a map of typical ENG truck coverage. The maps below show coverage and path loss examples for a typical LPTV station.
