u
RadiO transmission from under
ground antennae eventually will
s1percede transmission from the
outside aerial and will result in
Tie elimination Of fading, the.
Sbliteration of difficulties encoun-
teTed in day reception and in a
considerable reduction in power
required for transmission.
By means Of the underground
and submerged antennae, trans
oceanic communication will be-
come a commonplace.
DIR. Rogers Theory.
That, briefly, is the theory Of
DR.. James H. Rogers, who since
the birth Of radio, has been always
several jumps ahead Of other
scientists of the day in the develop.
ment Of wireless communication.
This magnificent man of science,
whose seventy-three years Of life
lie easily on his shoulders, expects
within the next few weeks to re-
sumo his experiments in support
OF his theory.
His laboratories at Hyattsville,
scene Of all of his past discoveries,
are ready for the return Of their
master, forced into involuntary
1dleness for several months by a
period Of i'll health.
Helped Win War.
It was in these laboratories that
o great role Of the world war was
played by DR.. Rogers and it was
! network Of underground antennae
! which listened in on many Of the
plans and secrets Of the German
= army and navy. And 1t was here
that. the methods Of ground and
water transmission adopted by the
American army and navy were
worked out by the inventor.
Last year experiments to prove
his theories Of ground transmission
were begun by DR.. Rogers, assist
ed by the Rev. Father Rafferty,, Of
Villa Nova College, Philadelphia,
and M. v. Flaherty, electrical en-
gineer for the Western Union.
The results Of the tests, however,
were never published. as DR.. Rog-
gle RIOAG44C0 ~ wall OA4SA4 AO A4GAA
completed the work.
Little Power Used.
In an interview yesterday DR..
Rogers discussed these tests and de-
clared that by tranmision from hi
underground antennae with tkree
five.watt tube perfect comrnunica.
ton was carried on between his
laboratory and Villa Nova College.
Reception also was reported at
Richmond, Parkerburg, w. Va, an0
in New Hampshire.
The power Of fifteen watts used,
he explained, was less than one
third the amount Of energy re-
CURED to light one ordinary electric
light bulb.
Under his laboratories, and under
practically the entire village Of Hy.
attsville, DR.. Rogers wheel of an
tennae stretch out in every direc-
ton. Until recently they were EN-.
ployed only in wireless reception.
The hub, together with the metal.
encased room and well in the lab.
oratories, will be used in the tests
to be conducted as soon as DR..
Rogers returns to work.
Proved His Theories.
It was with these appliances
that the scientist proved his thee.
RES Of ground reception. In the
metallic room, DR.. Rogers discov-
cred that by keeping the entire
room closed, no signals could be
ceived, but by removing the floor,
the signals came in strong and
clear through the ground.
Similar tests were worked out
successfully by using q loop an
tenna let down into q meta!-lined
and metal-covered we'll.
The cage loop antenna, incident
ally, is an invention Of DR.. Rogers
for which q patent is pending now
In the Patent Office. It 10 seldom
or never used by the inventor, who
employs his underground wires to
listen in nightly to foreign stations.
A high strung antenna on the roof
Of the laboratory likewise Is never
used and for several years has not
been connected to the laboratory.
After he had explained his
theories Of transmission" DR.. Rog.
ers was asked to predict the future Of
broadcasting.
Predicts Fewer Stations.
II believe 1t will be concentrated
very soon at a group of powerful
stations located at strategic inter-
walls over the United States" he
said. ''Then only the best of music
and the best of addresses, together
with all important audible events,
will be transmitted for rebroadcast.
ing throughout the country.
Interference from so many diff.
ferent wave lengths will be elimin.
ated and reception will be clear
and strong in every set.
The broadcasting stations will
operate with some sort of device like
a telephone switchboard, taking in
from other stations whatever pro.
grams they desire and rebroadcast.
ing them in their immediate vicin.
1ty."
Transatlantic and Trans-Pacific
communication very soon will be
nothing out Of the ordinary for
any listener-in, DIR. Rogers declared.
"But all of these things will come
only through the transmission from
underground antennae," he con-
Cluded.
