Anyone ever play around with the Radio Mobil Online webpage?
Radio Mobile WEB Site
You plug in antenna, wattage, frequency, location of transmitter and receiver, elevation of antenna, etc, and it predicts signal strength coverage.
I've been playing with it on and off all day today, plugging in different numbers, antenna height, playing with frequencies, etc.
I'm wondering if its generally accurate?
Some things I've learned playing with 13 miles between the Tx and Rx stations over minor hills and valleys..
*On the 2 meter band, there is absolutely no substitute for antenna height.. nothing even comes in close second.
*On 40 meters, just 2 watts goes a very long distance and goes everywhere.. Small hills and valleys may as well be flat land. 2 watts can easily make the 13 miles of distance I need.
*On 20 meters, its almost the same as 40 meters so far as a 13 mile distance is concerned.
So now I'm wondering how accurate and reliable the Radio Mobil site is. It seems to use google maps and topographical information to calculate for the terrain.
Any opinions?
