—

avoid

installing

the

antenna

where

it

can

be

bumped

or

jarred

by

people,

furniture,

doors

or

pets.

Also

avoid

installing

the

installation

—

try

avoid

an

installation

that

plate.

To

avoid

problems,

choose

an

installation

site

that

is

structurally

sound

and

able

to

withstand

severe

storm

conditions.

brush

the

snow

off

the

antenna.
