For example, you'll read in one of the comparison reports that a top competitor's advertised "Rife Machine" claims to output between 18 and 45.6 watts (their different sources). Our comparison report links you to videoed lab tests that clearly shows that these power wattage claims are not close to accurate. Their tested frequency devices were found to only output less than 1 watt each. More than one of their same devices were thoroughly tested and reviewed.

HIGHEST FREQUENCY RANGE

HIGHEST POWER OUTPUT

HIGH-RF CARRIER WAVEFORM

Power determines penetration. How well an instrument works is tied directly to the power output broadcast on a carrier waveform. With our SR-4 it is 75 to 150 times MORE powerful than our top competitor's frequency devices.

A variable high-RF carrier frequency is utilized to deliver more power to the intended 'targets' and make larger side-band sweeps possible. No other plasma tube instrument has this capability.

PLASMA TUBE POWERED

Huge time saver! Capable of outputting 2-8 frequencies simultaneously. We built a plasma ray tube instrument that can run 8 frequencies at a time with more than enough power for each frequency being broadcast.

The GB-4000, SR-4 and M.O.P.A. frequency generating instruments are the result of over 26 years of extensive research and development including feedback from in-home researchers and clinical reporting.

Full-range capacity...can run ALL of Dr. Rife's frequencies as used in the original Rife Machines. 1 to 20,000,000 Hertz. Other plasma devices on the market are limited from 10,000 to 400,000 Hertz.

Like the 1930s equipment, one can freely move around the GB-4000 enjoying the freedom of movement within its over 30-foot radius range. The additional 115-watts of power makes this possible. POWER IS VITAL FOR SUCCESS!

The M.O.P.A. plasma ray tube contains 2 noble gases, Argon and Neon, which is completely safe while offering the BEST signal emission for outputting single or multiple RF frequencies.

The Secret Weapon! Both the "SWEEP" function and the "CHANNEL SWEEP" function allows the GB-4000 frequency generator to output targeted frequencies sequentially in defined steps to achieve increased efficacy by allowing all "doors'" to be "knocked" on.

Our instruments are state-of-the-art frequency generating devices and we are the industry leader in customer service, training and professional support...all without an additional fee when you purchase directly from us.

SR-4 Linear Amplifier is used with the GB-4000.
The SR-4 allows the GB-4000 to output in RF (Radio Frequency) Mode. Over 110 volts peak-to-peak making it 18 times more powerful than nearly all other frequency generators on the market. RF power is KING!

The GB-4000 has a variable power output up to 4.7 watts and up to 15 watts with the SR-4 amplifier.

Capable of amplifying 8 frequencies simultaneously which makes it much faster to use when connected to the GB-4000 frequency generator. Your time is important to you so why waste it running only one frequency at a time?

The GB-4000 with SR-4 can output ALL of Dr. Royal Rife's frequencies in the millions of Hertz. POWER and a HIGH FREQUENCY RANGE in a generator system is vitally important. Request our FREE RIFE REPORT and learn why.

We don't call our frequency instruments Rife Machines or a Rife Machine like many other companies do. Dr. Rife specifically stated that he did not want his name put on any machine because "some people" might use his name to sell their own machines. Those companies who respect his wishes do not call their machine a Rife Machine. The function generator and amplifiers shown on this website are sold as electronic test equipment.
