Plasma tubes only transmit   1% to 3%  of the energy sent though them.  With metal antenna, nearly 100% energy transmission is achieved.  All modern electronics use metal antennas to transmit because they are more efficient. Television and radio stations, satellites, they all use metal antennas.

     The benefit of a gas tube (plasma) antenna is that it will create a good square wave, regardless of what is fed into it.  In Rife's time, this was the only way he could get a good square wave.  With the electronics available in the 1930's the plasma tube was required to produce a good square wave.   Now with modern function generators we can generate excellent square waves without the need for a gas tube.  This allows us to take advantage of the much more efficient metal antennas.

     Some may claim that the light created by a plasma tube has effect.  Light can only pass through about 1/8th of an inch of skin, (otherwise eyelids wouldn't work.)   The true effect is created by the radio wave energy transmitted.

     Considering that plasma tubes are usually 100 to 300 watts and 1% to 3%  efficient, these devices can only transmit 3 to 9  watts.  Our systems can transmit up to 150 watts at 95%+  efficiency making them 15 to 50 times stronger than anything else on the market.
