Quid enim a LXXV ohm aluminium fistulam cable compare ad aeris coaxial funem?

LXXV Ohm Aluminium Tube Cable vs aeris coaxial funem: A comprehensive collatio
Introductio
In RF (radio frequency) et broadband signum tradenda, LXXV ohm coaxial funibus Sunt late usus ad applications ut funem TV, satellite communications et CCTV systems. Duas communia sunt aluminium fistulam coaxial funes et traditional aeris coaxial funibus. Dum utraque eadem fundamentalis proposito differunt electrica perficientur sumptus diuturnitatem et installation flexibilitate.

Hoc articulum providet a detailed collatio inter LXXV ohm aluminium tubo funem et aeris coaxial cables, scrutandis eorum constructione, signum transmissionem efficientiam, cost-efficaciam, et optimum usu missionibus.

I. Construction et materiae differences
A. Aluminium Tube coaxial funem
Center Conductor: typically aeris-vesti aluminium (cca) vel solidum aluminium.

Skighting: Aluminium Tube (CONRUGIS aut lenis) Aluminium Foil Croid.

Dielectric: spumam polyethylene vel aeris-spaced dielectric.

Outeus Jacket: UV repugnans PVC et polyethylene.

Commoda:
LIBRICUS
Inferior
Bonum corrosio resistentia
Idoneam longum distantiam decurrit

Inadevantia:
Altior signum damnum solidum aeris
Minus flexibile (praesertim CONRUGIS Cogitationes)

B. aeris coaxial funem
Center Conductor: solidum vel aeris.

Skeping, aeris Braid aluminium ffoyle (vel duplex / triplex protegit).

Dielectric: solidum vel spumam polyethylene.

Outeus Jacket: PVC, PE, aut LSZH (humilis fumus nulla, halogen).

Commoda:
Superior conductivity (inferiori signum)
Melius flexibilitate
Superiore diuturnitatem in dura conditionibus

Inadevantia:
Magis pretiosa
Gravius ​​quam aluminium funibus

II. Electrical Euismod collatio
A. Signum damnum (ATTENUATIO)
Frequency (mhz) Aluminium tubo cable (DB / 100m) aeris coaxial cable (DB / 100m)
L 2.1 - 3.0 1.5 - 2.0
D 7.0 - 9.0 5.0 - 6.5
M 10.0 - 13.0 7.0 - 9.0
Conclusio:

Aeris cables inferioribus signo damnum faciens melius summus frequency applications.

Aluminium Cables gratum est brevior fugit vel minus frequentiis (E.G., CATV).

B. impeditance stabilitatem
Tum cables disposito LXXV ohm impedirentance, sed:

Aeris maintains impeditance melius per longum spatia.

Aluminium potest habere levi variationes ex vestibulum tolerances.

C. Shielding efficaciam
Times Type aluminium fistula cable aeris coaxial funem
Tactus / RFI Donec praeclara (Tube scutum) Bonum (Frigus FORMA)
Flexibilitate impulsum minus flexibile magis flexibile
Aluminium Tube cables providere superior protegit ex eorum solidum exterioris conductor, faciens ea specimen ad altus-intercessiones environments.

III. Mechanica et environmental diuturnitatem
Elementum Aluminium Tube Cable Cupia Cable
Pondus levius gravior
Flectere radius maior (minus flexibile) minor (magis flexibile)
ROSIO Resistance High (Aluminium Oxide Layer) moderari (nisi tinnulatur aeris)
UV Resistance bonum (cum Pe Jacket) bonum (cum PE / PVC)
Cóntere resistentia excelsum (rigidum structuram) moderatus (pendeat in protegit)
Usus optimus optimus:

Aluminium tubo funem: aeria installations subterranque ducts, diu distantia trunci lineae.

Cabes Cables, Wiring, flexibile setups, summus frequency signa transmissio.

IV. Custus collatio

Oeconomica considerations:

Aluminium est cost-effective pro magna-scale deployments (E.G., cable TV Networks).

Copper est maluit ad discrimine summus perficientur applications (E.G .: Satellite Feeds).

V. Installation et sustentacionem considerations
A. Aluminium tubo cable
Pros:

Facilius install in longum, recta decurrit.

Inferioris shipping costs propter lightweight.

Cons:

Requirit specialis connectors (compressionem-genus).

Difficile reparare si laedantur.

B. aeris coaxial funem
Pros:

Facilius ad terminare (vexillum F-Type / BNC Iungo).

Plus reparabilis.

Cons:

Gravior, ducens ad altiorem labore costs.

VI. Quod quis vis?
Elige aluminium tubo funem, si:
Opus diu distantia, humilis sumptus signum tradenda.
Tactus scutum est prioritas.
Installation est certa (aeria / sub).

Eligere aeris coaxial funem, si:
Signum integritas est discrimine (E.G., satellite, summus celeritate data).
Flexibility opus est (E.G., UMBRATILIS Wiring).
Potes praestare altius upfront costs ad meliorem Vivacitas.

VII. Future trends in coaxial cable technology
Hybrid Designs (Aluminium Aeris compositorum).

Melius dielectric materias pro inferioribus damnum.

Smart funibus cum constructum in signum magna.

Utrumque LXXV ohm aluminium fistulam funibus et aeris coaxial runnes habere vires et infirmitates.

Aluminium tubo funem sunt cost-effective, lightweight et optimum longum distantiae, tuta applications.

Aeris coaxial cables offerre magis signum qualis, flexibilitate et diuturnitatem, faciens ea specimen ad altus-perficientur necessitates.

Final commendaticiis:

Nam magna-scale, budget-conscious projects (E.G., CATV networks), uti aluminium tubo funibus.

Nam summus frequency, summus reliability applications (E.G., passim, satellite), investimus in aeris coaxial funes.
