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. The GB4000 20Mhz sweep function generator, SR4, and MOPA 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.

Greatest Frequency Range

Highest Frequency Range

The frequency range is very important! The original machines used frequencies from 120 Hertz to 17,033,000 Hertz. The GB4000 with the MOPA Amplifier and plasma tube is capable of emitting frequencies from 1 Hertz to 20,000,000 Hertz which is the largest frequency range of any plasma tube instrument today. Most other plasma tube instruments on the market are limited to a range of 1 Hertz to about 300,000 Hertz.

8 Frequencies at Once

Up to 8 Times Faster To Use

The GB-4000 has a powerful multi-signaling capability which makes it up to 8 times faster to use than other instruments. Your time is important to you so why waste it running only one frequency at a time? The GB-4000 can output up to 8 frequencies simultaneously with a variable 10 to 100% square wave duty cycle. 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 and you have to purchase 2 additional frequency generators at an additional cost of about $1200.00 each. Since the GB-4000 has the ability to output 2 to 8 frequencies simultaneously, up to 40,000 Hertz, it is like getting 8 frequency generators for the price of one, saving you thousands of dollars.

The GB-4000 also has the capability of running 2 frequencies from 40,001 Hertz to 20,000,000 million Hertz with either the MOPA or SR-4 amplifier. Some companies speak negatively about running multiple frequencies simultaneously, but the original 1930s/1950s instruments had the capability of running 10 audio frequencies simultaneously to 40,000 Hertz with a fixed 50% square wave duty cycle. The original equipment also had the capability of running more than 100 sideband RF (Radio Frequencies) frequencies simultaneously. Having this capability reduced run times significantly and is the reason we use this same method with our instruments.

Plasma Tube Powered

The Mopa Plasma Tube contains 2 noble gases - Argon and Neon. This combination of gases is completely safe while offering the best signal emission for outputting single or multiple frequencies. The MOPA's plasma tube is conduction lit which means that there are no internal metal electrodes that can contaminate the plasma tube gas. It only takes 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. 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 the MOPA 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.

Highest Power Output

More Than a 30-Foot Range

You can freely move around the GB-4000 with MOPA enjoying the freedom of movement within its over 30-foot radius range. You can sleep doing overnight sets, watch TV, read, cook, eat or work while receiving the frequencies delivered from the plasma tube. With the plasma tube reflector, it has a directional 180-degree range well over 40 feet which is the largest range of any plasma tube instrument on the market today. The additional 180-watts of power is what makes this possible. The original 1930s equipment demonstrated this range or capability.

Unlike other companies, we do not incorrectly claim that our plasma tube works on "Resonant Capacitive Coupling." All Plasma tubes that emit frequencies are subject to the "Inverse Square Law" which law governs all electro-magnetic waves (radio, light, X-rays, sound, gravity, etc.).

Freely Move Around

With the MOPA plasma tube instrument and the plasma tube reflector, you have the freedom to move all around within the MOPA's more than 40 foot range, all while getting the frequencies you desire. You need no wires, mats, plates, or metal cylinders! Instead of the frequencies being delivered via conductive accessories, the frequencies are broadcast by the plasma tube through the air for maximum ease of use.

MOPA Amplifier 

Highest Power Output

Highest Power Output

The GB4000 function generator works in conjunction with the SR4 amplifier or the MOPA Amplifier to give you the best possible power output available today in a frequency device. The GB4000 by itself is as much as 10 to 20 times more powerful than other machines on the market. When you add the SR4 amplifier, the maximum output power is up to 18 watts, which is as much as 75 times more powerful than other machines on the market.

For those looking for a non-contact device, the GB4000 and MOPA amplifier work together with the plasma tube to produce a maximum of 190 watts of radiant output power. If you are looking for a world class frequency machine with the best output power in the industry you have come to the right place.

Satisfaction Guaranteed!

We are sure that you will love your new GB4000! We are so sure that we offer a 60 Day Money Back Guarantee. We understand that you can't go to one of the big box stores to check out your new frequency machine before you buy. So order with the confidence that when you get your new equipment home you can get it out, use it, and make sure that it is right for you. If you are not completely satisfied you have the option of returning it for a refund. Note that there is a restocking fee for the MOPA Amplifier. Please make sure to check out our full return policy here.

Beware of other companies "90 Day Buy Back" policy. Some of those policies stipulate a 10% restock fee for each month that you have the machine before you send it back. So you could end up loosing 10%, 20% even as much as 30% of the cost of the unit.

Return Policy
