In other words, it isn't enough to determine the distance RFI
radiates, buy isolated property and cross your fingers. What you
really have to do, if you can afford the luxury of owning a lot of
land, is buy enough property to establish a buffer distance from
property you don't own. It's all about having control. The only way
to really prevent future RFI is to be able to control everything in
the environment of your receiving antennas. I've heard of hams buying
just enough rural property to fit a guyed tower in. Corn fields
abound and it is ham heaven. Then Farmer Joe kicks off, the kids sell
the farm next door to a developer and (these things go up in no time
at all) six months later the guy anchors are a few feet away from
yards with cheap vinyl houses full of junk appliances. Nose floor
goes from S0 or S1 to S9.
I believe the ideal is at least 500 feet in all directions from the rx
antennas. Enough land must be purchased to have control over that
distance.
Walt Disney learned this lesson. DisneyLand in Anaheim was not built
with any buffer. Cheap tacky motels and tourist traps sprang up right
outside the entrance much to Walt Disney's dismay. When he planned
Disney World in Florida, he established a phony shell company to
quietly buy up property in small parcels below the radar, all around
the theme park site. When Disney World was announced, he already
owned all the land around it.
