difference 80 long as it's entire length
Is stretched out.
Sometimes Il Is impossible to
either stretch the wire along the
roof or hang It over the side. In
that case II can be made into n biz,

The lead-in can be taken from any
part of the antcnna. and it ;he an

the lcad-in. When the wire has been
stretched into tho shape OF V Il liz
preferable To take the lead-in from
the point where ;he two lines Of tho
V meet.
The place where the lead.in comes
ih'o tho house must he carefully in
sulhted. often dirt and dust have
collected on the windowsills This
dirt and dust. which is largely from
smoke. Is carbon and a good CON

unless there has been careful ins,;la-
tion the sound will go into this dir,

Rubber covered wire is good 81
the iead-in.
The ground connection Is o. even
greater importance tnan the antenna.
You can receive signals without an
tenna. but you cannot without a
ground connection.
The ground conncctbn must =.

joints, and this Is more or less Of an
insuihior. You must take care To
clean out ali dirt from the pip..
II Is best To Use regular CON

ordinary hardware stores II Is no,
necessary TO insulate the ground
wire. Annunciator wire is best for
ground wire.
Test Bu1zcr Needed.

around FOR fifteen minutes and not

something. whether or not his de-

some sets have TWO binding posts
so that tn. autcnna can be connected
with one or Tho other of these. II
the set has small antenna. u should
be connected with one post u in

large antcnna, IL should he connected
with the other TO decrease The wave
length.
some SETS have leading Golf that
provides additional wave length. This
