2m vs 70cm coverage

posted Feb 12, 2016, 10:43 AM by Charles Boling
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.
440 MHz plot
146 MHz plot
146 + 440 MHz plot
