Detailed description

Skirtas radijo, kompiuterių ir aukštojo dažnio jūrinėms sistemoms, koaksinis kabelis RG214/U užtikrina signalo perdavimą su plačia pralaidumo juosta ir mažu slopinimu. Šis kabelis specialiai suprojektuotas darbui dažnių diapazone iki 11 GHz, leidžiančiame perduoti signalus be iškraipymų trumpais ir vidutiniais atstumais.

Konstrukcija ir techniniai parametrai

RG214/U atitinka MIL-C-17 standartus su M17/75-RG214 ir MIL-DTL-17 H: M17/190-00001 žymėjimu. Jo vidinis laidininkas yra 7x0,76 mm (3,17 mm²) sidabruoto vario lina, kurios skersmuo apie 2,3 mm. Izoliacija – PE, skersmuo 7,25 mm. Išorinis ekranavimas sudarytas iš dvigubo sidabruoto vario lino tinklelio, užtikrinančio 95 % vidinį ir 98 % nominalų išorinį dengimą, suteikiant puikią apsaugą nuo elektromagnetinių trukdžių. Kabelio išorinis skersmuo – 10,8 ± 0,18 mm, apvalkalas – juodas PVC.

RG214/U elektrinės savybės 20°C temperatūroje: charakteringoji varža 50 ± 2 Ω, maksimalus darbinis talpinimas 101 pF/m 1 kHz dažnyje. Slopinimas kontroliuojamas, siekiant šių maksimalių verčių: 10 dB/100 m 200 MHz, 28 dB/100 m 1000 MHz ir 197 dB/100 m 11000 MHz. Signalų sklidimo greitis – 0,66 c. Kabelis atlaiko 5,0 kV (AČ) viršūnių įtampą ir 3,7 kV (efekt.) nominalią įtampą, bandymų įtampa – 10 kV AČ.

Pritaikymas ir montavimas

RG214/U kabelis tinkamas tiek pastovioms, tiek lanksčioms įrengimo sistemoms sausose ir drėgnose aplinkose, atlaiko didelius terminį ir cheminį apkrovimus. Galima naudoti lauke pastoviosioms sistemoms. Ugnies atsparios savybės atitinka IEC 60332-1-2 standartą. Atitinka ES direktyvą 2011/65/ES (RoHS). Palyginimui, dažniau naudojami RG58 tipo kabeliai mažiau reikliesiems taikymams, tačiau RG214/U su dvigubu ekranu ir geba dirbti aukštesniuose dažniuose yra optimalus sprendimas sistemoms, kur signalo vientisumas ir mažas slopinimas yra kritiniai, pralenkiant plonesnių koaksinių kabelių charakteristikas sudėtingose jūrinėse aplinkose.

« 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 shield provides superior protection against electromagnetic interference compared to single-shielded cables like RG58 or RG8X, which is crucial in a marine 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 loss. 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.
