Hills, particularly large buildings, sometimes above ground
power/telephone/cable distribution (more an issue on 160 than 10,
certainly). The closer the building, the smaller it can be and
obstruct or attenuate signals.
Someone I knew was complaining about his vertical's low angle
performance. I went by his residence, and noted that the NE direction
was UP the street (literally), something like ten houses before things
It was a really nice neighborhood, and doesn't deserve the word
clutter, but for radio purposes NE it was.
When I lived in Albuquerque, the Sandia Mountains (10K+) were east of
me, and the lowest bit of sky east was up 25 degrees. Extremely
scenic, but qualifies as radio clutter.
