The usual panties with most

hard tubes for detectors as well as

experiment with a sort detector tube
as this tube is usually just as sensi-

strong one. and. in fact. is often
more sensitive on the weak signals:
A hard tube. on the‘ other hand,
is more sensitive to strong signals
than to weak ones.
The UV201‘A (Gaol-A) will give
best results for loud-speaker work. in
audio amplifiers, although the dry
cell tube will perform quite success-
fully in this respect.

You may have duncuuy‘ in erect-
ing an‘ outdoor antenna. While'lt is
possible to erect an aerial on nearly
every type of house, yet surrounding
trees, a slippery tile or peaked roof.
and other obstacles may make it a
difficult matter.
In crowded districts it is often im
possible to erect an antenna without
crossing or running parallel to a
number or nearby aerials. Or you
may be located in an . apartment
house where the landlord. for aesthe-
tic reasons. will not permiit the
erection of antennas on the root 0!
the building.
These facts may have deterred you
from building or buying a radio re-
ceiving set up to the present time.
I: you already possess a. set and are
bothered with considerable dirtleulty
in tuning out interference trom a
nearby station. the solution is to
build a. loop aerial.
New Circuits Require Loop
A great many of the new types
0: receiving sets such asthe reflex
and various radio :reuuenesr receiv-
ers really should be used with a
loop serial to secure. best results. A
loop is especially desirable With any
type or receiving set to reduce static
and gain selectivity or tuning.
The loop aerial has. certain dis-
advantages. The amount of energy
that can be picked up on. I. loop
aerial is very small as compared to
that received on even an indoor
aerial. The volume' 0! distant Its.-
tions will be much less. ’
It you have an outside serial at
the present time a loop will ban. Val~
usble addition for summer In. and
for trying out some or the newer
circuits. The picture diagram. shows
a novel means of incorporating s
loop aerial to your present receiv-
er, yet allowing for a very quick
ohsnge to the outside or indoor
aerial.
Double Grunts Milled
The construction or the loop.sn-'
tenns is novel in that an ordinary
telephone plug is inhioned on the
bottom end oi! the upright arm or
the loop. A double circuit jack is
then titted in the lid 0! the cabinet
of your radio receiver .0: better
still. tsste'ned to the rear or side of
the cabinet with a; hole bored thrd
the lid for the plug to go through.
To use the loop simply insert the
plug in the lock. The Jack sup-
ports the lop in an upright position
and allows it to be ROTATED with-
out the danger or faulty connectiohs
or messy wires. .
You will note that the two outside
connections on tho jack are wired
to the antenna and ground binding
When the
plug is inserted one contact or the

the other side is connecfiod tom the

are connected to the aerial
ground. When the plug is inserted
in the jack the aerial and ground
are automatically disconnected from
the receiver and the loop is placed
across the receiver binding“ posts.
When you remove the loop the in-
side connections or the jack melts
contact with the outer connections
thereby connecting the reciever to
serial and ground in the regular
