I have been running the location utilizing an omni-directional vertical antenna due to not knowing exactly the antenna which will be in place. That gives us a worst case scenario. While that is a great location – it might be too good. With the effective radiated power limit at max, the covered area is substantially larger than the original submission.
In power density: At the top of the large circle is Portland – with a large power density into it This was 10W with a less than half power gain antenna at 100 feet above ground level.
The same display in uV, but focused on the Salem /Turner area:
As you can see, the power level in the valley is very high even with the reduced power.
When I reduce the power level down further, the Portland directed lobe comes way down, as does the Albany direction. Salem and the other areas are covered nicely.
With better knowledge of the antenna and height above ground we can pull better data. It looks promising, but the lobes to the north and south would concern me – but the right antenna can fix that.
