The System-G Project : PHASE B
This new design of the System-G uses a Contrawound Toroidal Helical Antenna (CTHA) as a source of EM waves.
The Contrawound Toroidal Helical Antenna (CTHA) is a patented antenna ( US Patent # 5,654,723 ) developed at West Virginia Universitys Center for Industrial Research Applications (CIRA). One of the most remarkable characteristics of the CTHA is its ability to produce a nearly isotropic radiation pattern. The CTHA is also a ground plane independent antenna. During some comparative communication tests done by the Emergent Technologies Corporation (ETC), where all external parameters between a standard military monopole antenna, a dipole and a CTHA were equal, the CTHA outperformed the monopole antenna by a factor of 300%.
The principal reasons why I have choosen to use this antenna are :
A nearly isotropic radiation pattern,
The ground plane independent capabilities,
The height and the length of the antenna.
The CTHA consists of two helical windings along a torus shape. The resulting helix is chiral, the windings are wrapped along the axis of the helix as shown in the photos below.
In the picture above, the CTHA antenna is placed in the iron shield, not yet closed.
The System-G v2.0 was an attempt of a design which would not use the iron powder as a medium, only the iron shield would be used for absorbing the EM radiations. But some tests about the resonnance frequency (170 MHz) of the CTHA antenna in air ( see below ) has definitely convinced me that the use of a medium (such as the iron powder) for reducing the phase wave velocity is required.
frequency of this CTHA antenna in air is 170 MHz,
this has been measured with a Dip Meter (ALTAI Y140)
So, I have decided to fill the torus with iron powder so as to reduce the resonance freqency of the antenna.
The CTHA antenna
is fully immersed in the iron powder so that the EM waves will
propagate in this medium.
This will slow down the phase wave velocity and thus the resonance frequency will go down.
weight : 426 g
Total weight of the System-G : 9065 g
Now, the measurements with the Dip Meter between 1.5 MHz and 250 MHz have shown that there is no "dip" in this range and this confirms that the resonance frequency has dropped dramatically to 20 KHz ( see below ).
In the iron powder used as a medium the resonance frequency of the CTHA is now 20 KHZ.
This is very interesting because the working frequency of the CTHA antenna is now in the VLF range...
Now, this new measurement on the System-G v2.0 demonstrates clearly the first Aquino's claim :
- A VHF antenna encapsulated by a medium with permeability and conductivity is able to radiate power in the ELF/VLF range due to its reduction of the phase wave velocity.
During this tuning test, I have used a 200W audio amplifier fed by a Tektronix Function generator AFG310 set in sinewave mode.
System-G v2.0 : The CTHA measured datas
Resonance frequency : 20 KHz
Amp DC power input = 84.45 Watts.
In a next test, I shall use a new High Power MosFet Amplifier ( Rockwood ZX117) which is able to give up to 2000 Watts (set in bridged mode) of power output between 10Hz and 30 KHz ( +/- 1dB ). A function generator is used for generating a sinewave (Tektronix AFG310 ).
System-G v2.0 : Project status report on May 18th, 2000 :
I have not
yet tried to measure the weight change in the System-G, the power
flow in the CTHA is always too weak ( about 100 Watts ) for
expecting some significant weight modification of the apparatus.
I need to send at least 2 KW of ELF Power ( the best will be
about 8 KW ) in the CTHA antenna. Today the iron powder that I
have used doesn't match the required specifications ( perm=75,
cond=10 S/m ) for obtaining a good reduction of the phase wave
Now, I am convinced that the best way is to lower the working frequency at 50 Hz ( in Europe). At 50 Hz, I shall be able to connect CTHA directly to the power grid ( through an insulation transformer of course ).
In spite of appearance, this System-G device is not so simple to build. For a successful replication the "royal way" will be to replicate exactly the original setup from Fran De Aquino that fully detailled in this web site.
The testing is not yet finished, stay tuned...
