Using a similar process as I did several years ago to generate some RF propagation plots such these, I compared coverage on both UHF and VHF from up on Rainier Hill. I eliminated the geographical map background this time to make it easier to focus on the propagation rather than exact locations. Each pixel represents a 500m square, so the 600x600 plot covers a 150km radius, and you can pretty much figure out mountain placement, etc. from there. The westward rays on the 2m plot are over the ocean. |
