Re: Antenna Thoughts and Suggestions


 

Hi,
Radio Mobile is a toy...
Send me the coordinates and tx, antenna, cables etc parameters and I will try a real coverage simulation? with the ATDI's ICS Telecom professional tool.
I think there are 50 meters resolution DTM data for the USA on the web. (DTED 1 or 0 at least). The result will be in GE kmz format and can be seen on regular GE maps.

This evening, once again, I tried Radio Mobile. I tried it a few years
ago at the request of the frequency coordinator in eastern Idaho. And
again this evening with similar results. If only I had the coverage it
shows. It is nothing close to what I really have. It shows coverage way
far out from what it really is. Maybe it is close in the flat lands, but
sure isn't here in the mountains.
