GB-4000 - SR-4 - M.O.P.A.

Designed after years of research

Any 20MHz Sweep Function Generator can output all of the frequencies that were used in the original Rife Machine or Rife Machines. What they lack is power in their output. Power output always determines performance. The GB-4000 20MHz sweep function generator, SR-4 and M.O.P.A. frequency amplifying instruments are the result of over 24 years of extensive research and development and have the ability to output all of the original frequencies with the correct power levels needed.

Highest frequency range

Frequency range is very important! The original machines used frequencies from 120 Hertz to 17,033,000 Hertz. The GB-4000 with the SR-4 or the M.O.P.A. plasma tube has the capability of emitting frequencies from 1 Hertz to 20,000,000 Hertz which is the largest frequency range of any plasma tube instrument. Most other plasma tube instruments on the market today are limited to a range of 10,000 Hertz to 400,000 Hertz. All frequencies are output analog using a DSP or a DDS.

Up to 8-times faster to use

The GB-4000 uses 2 powerful multi-signaling capabilities which makes it up to 8 times faster to use than any other frequency generator. The reason it is faster to use is due to the fact that it is the only frequency generator with the ability to run from 2 to 8 frequencies simultaneously from 1 Hertz to 40,000 Hertz and 2 frequencies from 40,001 Hertz to 20,000,000 million Hertz for a superior multi-frequency waveform. Almost 95% of all the frequencies which people use are under 40,000 Hertz saving you many hours of time. Your time is important to you so don't waste it running only one frequency at a time with other instruments. The average run time per frequency is from 3 to 5 minutes. If you run 8 frequencies for 5 minutes each it would take you 40 minutes to run all 8, but, with the GB-4000 it will only take 5 minutes to run all 8 simultaneously.

Only one other company has this multi-signaling capability, but they have a major drawback.  They are limited to only 3 frequencies simultaneously but you have to purchase 2 additional frequency generators at an additional cost of $1200.00 each. Since the GB-4000 has the ability to output 2 to 8 frequencies simultaneously you are getting 8 frequency generators for the price of just one, not only saving you time but thousands of dollars. The original 1930s/1950s instruments had this capability.

Most powerful waveforms

The original instruments only used three different waveforms and for this reason, we use the same three waveforms with the GB-4000, SR-4, and M.O.P.A. These waveforms were sine wave, damped wave, and square wave. Of the three waveforms the square wave is the most powerful of all the waveforms. In 1936 the damped wave was replaced with a square wave because it proved to be far more powerful. Some companies promote the use of other less powerful waveforms that were never used. For this reason we only use the proven waveforms.

User interface

When you are operating a frequency generator the last thing you want to do is fight the user operational interface in order to get it to produce the frequencies you want to use. With the GB-4000 there is no toggling of only a few buttons or scrolling through endless lists of options and numbers to get to the function you want to use. The GB4000 has a full function keypad with all the functions and numbers you need directly accessible making it very easy to use.

Highest power output

The GB4000 by itself in “RF Mode” outputs 4.7-watts which is as much as 47 times more powerful than other machines on the market. When you add the SR4 15-watt amplifier the power output is as much as 150 times more powerful than other machines on the market.

For those looking for a non-contact device, the GB4000 and M.O.P.A. amplifier work together with the plasma tube to produce a maximum of 190 watts of radiant power output. If you are looking for a world-class frequency machine with the best power output capable of running 8 frequencies simultaneously you have come to the right place.

Plasma tube powered

The M.O.P.A. plasma tube contains 2 noble gases, Argon and Neon, which is completely safe while offering the best signal emission for outputting single or multiple frequencies. The M.O.P.A.’s plasma tube is conduction lit which means there are no internal metal electrodes that can contaminate the plasma tube gas. It only requires about 2 watts of energy to light the plasma tube which means it is rated for tens of thousands of hours of use without any output degradation or power loss. We have many plasma tubes that are still working like new even after more than 10 years of continual use. 

A Plasma tube eliminates the necessity of having a tuned metal antenna for maximum power output. The GB-4000 with M.O.P.A. has the highest frequency range output of any plasma tube instrument on the market today and gives you more possibilities now and in the future.

More than a 30-foot range

You can freely move around the GB-4000 with M.O.P.A. enjoying the freedom of movement within its over 30-foot radius range. You need no wires, mats, plates or metal hand cylinders when using the MOPA because the frequencies are broadcasted by the plasma tube through the air for maximum benefits. You can sleep doing overnight sets, watch TV, read, cook, eat or work while receiving the frequencies delivered from the plasma tube.

The plasma tube has a removable reflector and most people use the plasma tube with the reflector. This gives it a directional 180-degree range well over 40 feet. This is the largest range of any plasma tube instrument on the market today. The additional 115-watts of power is what makes this possible. The original 1930s/1950s equipment had this same range capability.

60 day money-back guarantee


We offer a 60-day money-back guarantee less a 10% restocking fee to cover shipping, handling, and repackaging. Returned equipment must be returned in the original condition and sent back in the original boxes.

Two years warranty

The GB-4000, SR-4 and *M.O.P.A. amplifier have a full two-year *limited warranty on parts and labor. (Only exception: 90 days on 812a vacuum tube.) This 812a vacuum tube should not be confused with the Pyrex Plasma Gas Filled Tube which will last for more than 15 to 20 years.

1/2 price replacement guarantee

No other company has the confidence in their equipment to offer this type of replacement guarantee. The GB4000 and its companion amplifiers are designed and built to last for many years. Even when the unit is outside of the warranty period, almost any issue that comes up can be easily and inexpensively repaired. However, we have seen some instances where a machine is damaged beyond repair by electrical spikes or other catastrophic conditions. If this should happen at any time after the 2-year warranty has expired and your GB-4000, SR-4 or M.O.P.A. circuit board or boards cannot be repaired by the factory, you will have the option to replace the circuit board or internal components for half the price of a new unit.  

This 1/2 price replacement guarantee offer applies to all current and previous models of the GB4000, SR-4, and M.O.P.A.  All shipping cost to the factory and return shipping to the customer is paid by the customer. We stand behind our products and believe in taking care of our customers for life.

Lifetime Support

We understand that you may need technical support. This is the reason why all of our products come with unlimited access to LifeTime support even if you are not the original purchaser. The LifeTime support is for the instrument, not the purchaser. If you have any questions after purchasing our instruments you can call and get professional help no matter what your needs may be, we are just a phone call away.


 

DISCLAIMER:

We do not call our 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 machines. Companies who respect his wishes do not call their frequency generating equipment a Rife Machine.
