Think of "The Distance Away" from Sources of Noise as
being your Friend. [ Less Noise -and- Stronger Signals ]

# 1 - 10-25 Feet "Away From" The House / Structure.
# 2 - 10-25 Feet "Up Above" The Ground / Surface of the Stucture.
# 3 - Combining both #1 and #2 are even better.
As you move the Antenna Element 'away-from' things
that are the Sources of RFI /EMF the Signal Strength
of the Noise becomes Less by the Square of the Distance
Distance and Signal Strength
1-Foot-Away = 1 Unit of Signal Strength relative to 1-Foot-Away
2-Feet-Away = 1/4th Unit of Signal Strength relative to 1-Foot-Away
3-Feet-Away = 1/9th Unit of Signal Strength relative to 1-Foot-Away
4-Feet-Away = 1/16th Unit of Signal Strength relative to 1-Foot-Away
5-Feet-Away = 1/25th Unit of Signal Strength relative to 1-Foot-Away
10-Feet-Away = 1/100th Unit of Signal Strength relative to 1-Foot-Away
15-Feet-Away = 1/225th Unit of Signal Strength relative to 1-Foot-Away
20-Feet-Away = 1/400th Unit of Signal Strength relative to 1-Foot-Away
25-Feet-Away = 1/625th Unit of Signal Strength relative to 1-Foot-Away
Now if the Signal Strength of the Broadcast Signals at each
Distance were to remain the same : Then the Relative
Signal-to-Noise Ratio would run-out like this :
1-Foot-Away = Signal-to-Noise Ratio = 1:1
2-Foot-Away = Signal-to-Noise Ratio = 1:1/2 ~ 2:1
3-Foot-Away = Signal-to-Noise Ratio = 1:1/9 ~ 9:1
4-Foot-Away = Signal-to-Noise Ratio = 1:1/16 ~ 16:1
5-Foot-Away = Signal-to-Noise Ratio = 1:1/25 ~ 25:1
10-Foot-Away = Signal-to-Noise Ratio = 1:1/100 ~ 100:1
15-Foot-Away = Signal-to-Noise Ratio = 1:1/225 ~ 225:1
20-Foot-Away = Signal-to-Noise Ratio = 1:1/400 ~ 400:1
25-Foot-Away = Signal-to-Noise Ratio = 1:1/625 ~ 625:1
The Bottom Line : Distance 'away' from Sources of Noise
is your Friend.
BEYOND THIS IS - The Ever Expand Sources-of-Noise
[ Circles-of-Noise in a World Full of Noise ]
1 - Starting with the Primary Point-of-Noise
[ First Circle of Noise ] Remember -It All Begins With You.
= = = Your Very Own House (1X-to-the-X)
2 - Second Circle of Noise
= = = The Houses of your Next-Door-Neighbors (8 X/Distance Away)
3 - Third Circle of Noise
= = = The Houses of your Near-by-Neighbors (64 X/Distance Away)
4 - Fourth Circle of Noise
= = = The Houses within your Neighborhood (512 X/Distance Away)
5 - Fifth Circle of Noise
= = = The Houses and Buildings in your City (16K X/Distance Away)
6 - Sixth Circle of Noise
= = = The Everything in your State (4M X/Distance Away)
7 - Seventh Circle of Noise
= = = The Everything in your Nation (256M X/Distance Away)
8 - Eigth Circle of Noise
= = = The Everything in the World (66B X/Distance Away)
9 - Ninth Circle of Noise
= = = The Everything in the Solar System (4T X/Distance Away)
All That Noise - It's beginning to Boogle-the-Mind
-but- Our Friend "Distance" Helps Out !
