Detailed description

Izstrādāts sarežģītiem radio, datorsistēmu un augstfrekvences jūras vides apstākļiem, koaksialkabelis RG214/U nodrošina signālu pārraidi ar plašu frekvenču joslu un zemu vājinājumu. Šis kabelis ir paredzēts darbam līdz 11 GHz, nodrošinot signālu izplatīšanos bez izkropļojumiem vidējās un īsās distances.

Konstrukcija un tehniskās īpašības

RG214/U atbilst MIL-C-17 standartam ar M17/75-RG214 un MIL-DTL-17 H: M17/190-00001 apzīmējumu. Tā iekšējais vads ir sudraba apzeltīts 7x0,76 mm (3,17 mm²) vītnes veidā ar aptuveni 2,3 mm diametru. Izolācija ir no PE, 7,25 mm diametrā. Ārējais ekrāns sastāv no dubultā sudraba apzeltīta vara vītņu apmales, nodrošinot 95% iekšējo un 98% ārējo pārklājumu (nominālā vērtība), kas nodrošina izcilu elektromagnētisko traucējumu aizsardzību. Kabeļa ārējais diametrs ir 10,8 ± 0,18 mm, ar melnu PVC apvalku.

RG214/U elektriskās īpašības 20°C temperatūrā ietver raksturīgo impedanci 50 ± 2 Ω un maksimālo darba kapacitāti 101 pF/m 1 kHz frekvencē. Vājinājums ir kontroles pakļauts, ar maksimālām vērtībām 10 dB/100 m 200 MHz, 28 dB/100 m 1000 MHz un 197 dB/100 m 11000 MHz. Signāla izplatīšanās ātrums ir 0,66 c. Kabelis iztur 5,0 kV (RF) virsspiedienu un 3,7 kV (efektīvā) nominālo spriegumu, ar 10 kV AC pārbaudes spriegumu.

Pielietojums un uzstādīšana

RG214/U kabelis ir piemērots gan fiksētām, gan elastīgām instalācijām sausos vai mitros apstākļos, un iztur augstu termisko un ķīmisko slodzi. To var lietot ārpus telpām fiksētām instalācijām. Tā izturība ir pastiprināta ar ugunsizturības atbilstību IEC 60332-1-2. Tas atbilst ES direktīvai 2011/65/EU (RoHS). Salīdzinot ar kabeliem, piemēram, RG58, kas paredzēti mazāk prasīgu pielietojumu, RG214/U ar savu dubulto ekrānu un augstāku frekvenču pārraides spēju ir risinājums instalācijām, kur signāla integritāte un zudumu samazināšana ir kritiski svarīgi, pārspējot sīkāku koaksialkabeļu veiktspēju sarežģītos jūras vides apstākļos.

« RG214/U: the technical choice for your critical RF links »

The RG214/U coaxial cable is a technical solution for demanding high-frequency connections aboard. It is particularly relevant for VHF/HF communication systems, radars, and marine computer networks where signal stability and integrity are paramount. Its construction with a double silver-plated copper shielding provides superior protection against electromagnetic interference compared to single-shielded cables like RG58 or RG8X, which is crucial in a nautical environment saturated with electronic equipment.

This type of cable is ideal for medium to large vessels requiring longer cable lengths or high-frequency transmissions (up to 11 GHz) with minimal losses. Its 10.8 mm diameter and robust PVC jacket make it suitable for fixed installations in the bilge, mast, or deck, even outdoors, with a minimum bending radius of 6 times the diameter for fixed installations. Installation requires expertise in connector assembly (UHF, N-type, BNC) to ensure 50 Ω impedance and shielding performance. Incorrect termination can negate the cable's advantages. Its cost per meter is justified by its enhanced performance and durability, positioning it as an investment for long-term reliability of onboard systems rather than an economical option for occasional needs.
