How to avoid amplification losses when using radio frequency
BEFORE you purchase a radio frequency transformer be sure to find this out. Does it show marked depressions and peaks in the amplification range between 250 and 500 meters? No amplification is possible in such depressions. Getting distant stations becomes a gamble as to whether or not there is any amplification at a given point.
How to get uniformity
THERE is a radio frequency amplifying transformer which has been so perfected that the peaks and depressions are eliminated. This is the Acme R-2. This unique transformer, after
long months of experimentation, has been perfected with a special type of iron core and windings which eliminate the peaks and depressions and provide a steadily increasing volume of amplification up to the point of maximum importance — 360 meters.
Gets greater distance
EQUALLY important is the far greater distances you get broadcasting. The Acme R-2 used in a r*adio frequency amplifier builds up wave energy before passing it on to the detector. You hear signals or
dinarily inaudible. The simplest and most elementary type of set, either vacuum tube or crystal receiver type, will have its range tremendously increased.
The best rnethod
To SECURE maximum results use three stages of Acme Radio Frequency Amplification (R-2, R-3 and R-4), a crystal detector and three stages of Acme Audio Frequency Amplification. This insures maximum sensitivity and intensity, quietness in operation and freedom from distortion. A small indoor antenna or loop may be used and sufficient intensity obtained to operate the Acme Kleerspeaker, providing perfect entertainment for a roomful of people. You can get these and other Acme Products at radio, electrical andmany hardware stores. Write for booklet R-2 showing proper hook-ups and other information.
