Hi all. I have been playing with antenna placement in my yard and I found a sweet area that can get 50% of the digital stations available. I then went to 100000watts.com and looked at power ratings. It seemed like the ones I am getting are 600kw+. So, I wrote a letter to a local stations (channel 39 UHF) and asked if they planned to up the power. He told me they were at the max power that the FCC would allow for channel 39.
I understand that as the frequency goes up, less power is required to get the same amplitude in the signal due to the shorter wavelength. It just seems weird that channel 30 is at 625KW, channel 42 is at 725KW, and channel 39 is only at 135KW.
Here's my question. I have trees in the yard. Other than that, I have a clear line of sight to the transmitting towers about 40 miles away. If after fine tuning the pitch and vector of the antenna, I still don't get the other channels, should I try stacking vertically(higher gain) or try stacking horizontally (fix multipath). Keep in mind that there is a guy about 4 miles away that has his antenna 60' up and clears the tree line. He gets all of the stations.
Is there a way to tell if the problem is signal strength or multipath? Thanks.
