The irregular ultra high friquency local area networks (UHFRLAN)
The UHF-radiowaves is a mostly effective for a radiosignal transmission. In practice all UHF-ranges is licensed but we have some noise in the listening with this ranges then can work without license because of an ordinal recievers and a radioscanners can not hook such signal that can be listen by an UHF-matrix and can not be listen by classic equipment.
Ordinally an UHFRLAN-transmitters has output power equal to around 1 mkW and this power is less than output power by the mobile phone. The speed of data transmission is a greatest.
The handmade design of an UHF-antenna: a sigarettes pack box with an aluminium foil inside is an improvisation UHF-waveline. An UHF-matrix has capacity connection with a sigarettes pack box as an UHF-antenna. The UHF-matrix has an USB-connector to an IrDA-adapter for connection to the reciever or the personal computer.
The UHF-matrix processor save short timing "windows" when an UHF-matrix listen and other equipment as an adapters does not a noise with a harmonics. The personal computers has an empties timing "windows" too.
The quality is a main characteristic of an UHF-antennas (an ordinally this value is signed as "a Q"). Must be more "Q" for a longer distance of the listen smallest radiosignals.
An UHF-antenna as a sigarettes pack box will work with a sigarettes too because of a sigarettes made from the dielectric materials.
What level of the sensitivity UHF-matrix reciever system?
If the handmade UHF-antenna area of an aluminium foil is an equal to 1 quadrate meter then we can listen a signal with output power 0.1 mkW with the distance to 1...1.5 km. Let's compare: a radioamateurs radiostation for a friquencies 144...146 MHz with the output power 0.1 W (100 mW) can be listen with each distance.
On this photo does shown empty energy drink aluminium tube as an UHF-waveline (an UHF-antenna). We can use an empties beer tubes. If you shall many beer tubes (f. e. 100...200) then you shall have very effective listening in an UHF-range for a friquency XXX GHz.
This is a metallized plastic pocket pack for a tea. The mirroring inside the pack will provide the smooth UHF-resonanse.
All CD and DVD discs has a thin aluminium metallization layer under the pictures. This aluminium layer has a some UHF-resonanse effect for a listening with an UHF-matrix.
We can have real amaizing with many photographies because of a smallest metal crystal clusters in the light sensitivity layer of the photorgaphy can takes some an UHF-resonanse in a range XXX...XXX THz.
The bestest effect takes by a black&white photographies on the older photopaper (that is manufactured in a period 1970...1990 years) and the X-rays glass photoplates and in a plastic photoplates and 35-mm photofilms too.
Once more handmade variant of an UHF-antenna is a glass or a plastic tube with the aluminium powder or a cutted XXX проволоки: the many holes between a metal particles will work as an UHF-circuits. Hair metallization by the gold or the silver or the aluminium in the vacuum post makes many thinnest pipes for the XXX GHz friquency an UHF-resonanses.
One from many researches by a students has present "a nanopipes" that base on a crystals that is named as "a vanadium wiskers" with the metallization with a gold then a vanadium wiskers after a metallization must be remove by a chemical methods. The result will be nanometric golden pipes that can work as an UHF-wavelines.
For an UHF-diods quality increase an UHF-matrix often cooled by the liquid gases with the deep frost.
On photo: an UHF-wavelines. The diameter must be calculated with noise conditions in the works friquencies in an UHF-range. Let get a friquencies then to calculate this to the wavelengths then calculate that to the internal aluminium foil pipes diameters. The many pipes get the greatest effect for an UHF-listening.
The UHF-wavelines as a mirorrs
All UHF-wavelines that has placed from the transmitter to the reciever can work as an UHF-mirorrs for a greater distances getting. The some TV-station has used this principle in early designs around 70th.
What is it? This is "a Passive Fider System" (a PFS): the many UHF-antenna elements is an installed in an one base. The PFS is a re-transmitter of the radiosignals in the work friquencies with an UHF-wavelines and without any amplification schemes.
This figure show a TV-signal from the transmitter (W1) that takes up through a PFS that installed on the mountain peak then can be listen in the W2 point. This PFS design is a many aluminium halfwave dipoles that has work as many mirrors on mountain peak. The TV-signal can not run through mountain with way 2 then can do it with way 1 easy.
The passive fider line for an UHFRLAN
That PFS can be disigned with the empties beer tubes that need to drop on the ground from an input point to an output point with the 1...10 m step.
The UHF-signal run from one tube to the next tube without a decrease or with smallest decrease of a power. We can make a connection through such method between two and more buildings as an unvisible connection radiosystem design.
This is a sample of a PFS with step distance between empties beer tubes is equal to 5...10 m.
The some empties beer tubes takes up an UHF-signal power in this place.
On photo: the simple power off method. Any beer tube that has loss form can not work as an UHF-waveline.
See with a humor to so strange an UHF-waveline: the bottle from a beer has a metallized label that can work as an UHF-waveline with the metallized layer of label. Really this work with good effective an UHF-power level in an UHF-matrix. How many non-controlled radiochannels we can have with this simplest designs in an UHF-range?
Plastic bottle with a metallized by the aluminium layer: a good way for an UHFRLAN-designs. This layer can not an oxydes under water or under snow.
Does not without humor because of this does works: an internal diameter of a Russian vodka aluminium cover is an equal to the calculated work UHF-friquency XXX GHz value diameter XXX is mm.
The metallized aluminium layer on a paper pack box can be work only when this is a dry. The water in a paper will decrease an UHF-power level.
For effective work the beer tube must has "a key" is an unbroken.
Sometimes a loss in a wood CD can show that an UHFRLAN is installed near.
An empty plastic pocket with an aluminium metallization has provide an increase of the UHF-signal power level. No any magic that is a simple physics laws!
For design of the directional UHF-waveline we can use a simple Sat-TV parabolic antenna that can be installed in the hidden place in a room that is near to window with the mask screen. You need to turn off an UHF-cable and to lay this cable on an UHF-matrix. An UHF-signal from the TV-SAT antenna will run to an UHF-matrix through a cable metal screen.
