The first is to show advertisers the area a station covers. Mobile Antenna Gain – this is the gain of the receiving antenna on the mobile station that will be used to determine your coverage area. The default will work for most situations. is a cross-platform, open-source software that can be used to analyze a radio link between two locations and to generate coverage maps of RF transmitters. 0000001293 00000 n Either way, there is a quick and easy way to generate RF coverage maps for … Please note that the value for this field is in dBi (isotropic) – if your antenna has a dBd (dipole) value, you can covert dBd to dBi by adding 2.15 dBi (i.e. This example of tx1.dcf will paint all areas with signal above -50 dBm in green color and all areas with signal between -50 dBm and -80 dBm as yellow. Those databases are located on the server and represent a total of 198 GigaBytes. Let's mention that SPLAT! Antenna Azimuth – this is the direction that your antenna will be pointing, with 0° being north. Using the Object Editor, Route lines can be drawn on the map using waypoints and saved for future use. About Radio Mobile The resource is currently listed in dxzone.com in a single category. These maps are generated using the same data and most of the same algorithms that the FCC uses when trying to predict coverage of radio stations and interference with other nearby radio stations. It was extremely handy for doing quick plots, giving insight into terrain obstacles, and allowing the user to do some quick comparisons of different transmitter sites or power levels. 35 0 obj << /Linearized 1 /O 40 /H [ 1293 254 ] /L 1106283 /E 9136 /N 3 /T 1105465 >> endobj xref 35 22 0000000016 00000 n Statistics show that in the periode  2012 to 2015, 663304 studies have been performed and that 26198 acoounts have been created. Once you enter this information, you will receive your password to enter the site via the email address you provided during registration. To do this, select the “New Coverage” option in the menu. Antenna Height – this is the height of your antenna above the ground at that specific location. Coverage maps are calculated using Longley-Rice Irregular Terrain Model (ITM) algorithm. As of this incomplete information or invalid operation can occur. One of the biggest factors is your radio; some radios will perform much better than others in trying to pick up distant radio stations. For added precision, you can also include the power loss in your connectors as well. SPLAT! Similar to the situation with Radio Mobile there is no real documentation avaialable from the author. Radio Station Coverage Maps: Promotional and engineering coverage maps: About the coverage maps: Coverage maps can have two purposes at a radio station. In contrast to inaccurate "HAAT" (Height Over Average Terrain) estimations, we use highly accurate computerized radio propagation modelling tools which have a detailed terrain model. To cover this issue a website with documentation is available at http://radiomobileonline.pe1mew.nl, Radio Mobile online can be found at http://www.ve2dbe.com/rmonline.html. 0000004953 00000 n The result is the following: Generating path loss map is not very different. The advantage of the online version over the traditional program that runs on a PC is that the user is not troubled by the administration of geodata like ground height of map data. The interface feels a little simplistic, but it does get the job done. To adjust colors, you need to make a different configuration file, with the same name as the QTH file and with the extension SCF for signal levels expressed as dBuV/m or DCF for signal expressed as dBm. I don’t use either of these tools a lot because I have other commercial software to generate coverage contours and do terrain-sensitive coverage analysis. Color for a successful reception (for coverage only), Color for a successful reception with a strong signal (for coverage only), Transparency of the ground overlay (for coverage only). The procedure of installing SPLAT! Once you have defined your transmitter location, it is now time time create a RF coverage map for that location. Select your location using the pull down menu. TX Power – this is the power output of your transmitter in Watts. The longer the feed line, the higher this value will be. Radio Mobile Online is a radio wave propagation prediction tool created and maintained by Roger Coudé, VE2DBE, which is dedicated for use by the ham radio community. 0000001092 00000 n For more information see: Radio Mobile Online is a popular tool to use. Take a look at some example radio coverage maps on the Examples link in the menu above. The interface feels a little simplistic, but it does get the job done. @� Mobile Antenna Height – this is the height of the receiving antenna on the mobile station that will be used to determine your coverage area.
