M.O.P.A. Combo Pack

M.O.P.A. Combo Pack


Now you can get the power of the M.O.P.A. Amplifier with the powerful features of the GB4000. The MOPA amplifier was designed based on an in-depth analysis of the equipment used by the original frequency researchers.

Though it has been updated with modern electronics, it still uses the RF tank coil and 812a vacuum tube needed to produce the original analog sine wave and square wave output of the original equipment.

  • Includes the GB4000 and the MOPA Amplifier
  • Hands-Free operation, non-contact frequency delivery
  • Only system on the market that can output the 1930s/1950s frequencies
  • Built-in frequency counter for easy configuration
  • Comes with full 2 year warranty

Why buy the GB-4000 with the M.O.P.A.?

Hands Free

Hands Free Operation

The M.O.P.A. is a non-contact 190 watt output instrument that allows the user to move around freely. By using the Plasma Tube to broadcast the frequencies, you are able to receive the frequencies without being tied down to the hand cylinders or foot pads.

You can sleep doing overnight sets, watch TV, read, cook, eat, or work while receiving frequencies delivered from the plasma tube. Keep in mind that the closer you are to the tube, the greater the power that is received by the user.

  • Plasma Tube has 5 foot leads for convenient positioning
  • Plasma tube uses a removable reflector to focus frequencies forward
  • Accessory Kit and Plasma Tube sold separately.

Highest Power Output

Highest Power Output

The GB4000 function generator works in conjunction with the MOPA amplifier to give you the highest possible power output available today in a radiant frequency machine. The MOPA has a variable output in the range of 20 watts to 190 watts.

This output is broadcast through the Plasma Tube, which is a glass or Pyrex tube filled with a noble gas. A plasma tube, unlike a metal antenna, has the capability of emitting frequencies over a very broad range without the need of being tuned.

  • Variable Power output up to 190 watts
  • User has complete control of output intensity
  • Up to 30 to 40 foot effective range

Perfect Accuracy

Best Frequency Range with Perfect Accuracy

The GB4000 with the MOPA has been designed to be able to produce all of the frequencies that the original researchers used. And now with the ability to operate in both the audio and RF modes, the MOPA has the broadest frequency range of any radiant frequency machine on the market.

  • Uses a variable RF carrier from 2.2Mhz to about 3.8Mhz
  • Can produce the high frequencies used by the original researchers
  • Frequency Range - 0.1 to 20 Million Hertz
  • MOPA can now operate in both Audio and RF modes.
  • Built in Frequency Counter for easy set up

Easy to Use

Easiest User Interface

When you are running your frequencies, the last thing you want is to have to fight your machine to get it to produce the frequencies you want. With the GB-4000 there is no scrolling through endless lists of options and numbers to get to the function you want. The GB4000 has a full keypad with all the functions and numbers you need directly accessible so it is extremely easy to use.

  • Full keypad for instant access to all functions
  • Comes pre-programmed with over 870 Channels - ready to use right out of the box
  • Can store up to 2000 Channels. All the room you need for your custom channels
  • Easy to use sweep and gating functions
  • Displays frequencies on the screen and in the manual - no hidden frequencies
  • Fully programmable. No need to ever buy other frequencies or recordings. You can program and run any frequencies from 1 Hz to 20 Mhz
  • Comes with Video Tutorial DVD

8 Frequencies at Once

Run up to 8 frequencies at once.

The GB-4000 is the only Frequency Machine that is capable of running up to 8 frequencies simultaneously to 40,000 Hertz without frequency degradation. Some people call it Multi-Signaling. And the GB4000 comes with that capability straight out of the box. No need to purchase additional equipment like some other machines on the market.

Running up to 8 frequencies at a time makes it up to 8 times faster than any other instrument. Why waste your time running one frequency at a time? And since the GB-4000 is so much more powerful than most other machines available, it has plenty of horsepower to run those frequencies at the same time. It's like getting 8 frequency generators for the price of one.
