Detailed description

Namenjen zahtevnim okoljem radio, računalniških in visokofrekvenčnih morskih sistemov, koaksialni kabel RG214/U zagotavlja prenos signalov z visokim pasovnim pasom in nizkim dušenjem. Ta kabel je posebno zasnovan za delovne frekvence do 11 GHz, kar omogoča nepopačen prenos signalov na kratke do srednje razdalje.

Konstrukcija in tehnične lastnosti

RG214/U je izdelan v skladu z normami M17/75-RG214 po MIL-C-17, z oznako MIL-DTL-17 H: M17/190-00001. Notranji vodnik je opletenka iz srebrenega bakra 7x 0,76 mm (3,17 mm²) z premerom približno 2,3 mm. Izolacija je iz PE z premerom 7,25 mm. Zunanji oklop sestavljata dvojna opleta iz srebrenih bakrenih žic, ki zagotavljata notranjo pokritost 95 % in zunanjo 98 % (nominalna vrednost), kar zagotavlja odlično zaščito pred elektromagnetnimi motnjami. Zunanji premer kabla je 10,8 ± 0,18 mm, z ovojnico iz črnega PVC-ja.

Električne lastnosti RG214/U pri 20°C vključujejo karakteristično impedanco 50 ± 2 Ω in maksimalno delovno kapaciteto 101 pF/m pri 1 kHz. Dušenje je nadzorovano, z maksimalnimi vrednostmi 10 dB/100 m pri 200 MHz, 28 dB/100 m pri 1000 MHz in 197 dB/100 m pri 11000 MHz. Hitrost širjenja je 0,66 c. Kabel podpira vršno napetost 5,0 kV (HF) in nazivno napetost 3,7 kV (efektivno), z preizkusno napetostjo 10 kV AC.

Uporaba in vgradnja

Kabel RG214/U je primeren za fiksne ali fleksibilne vgradnje v suhih ali vlažnih okoljih in odporen na visoke toplotne in kemijske napetosti. Lahko se uporablja v zunanjih fiksnih vgradnjah. Njegova robustnost je okrepljena z ognjevarnostjo v skladu z normo IEC 60332-1-2. Usklajen je z direktivo EU 2011/65/EU (RoHS). Za primerjavo, medtem ko se kabli, kot je RG58, pogosto uporabljajo za manj zahtevne aplikacije, se RG214/U s svojim dvojnim oklopom in sposobnostjo obvladovanja višjih frekvenc, postavlja kot rešitev za vgradnje, kjer je integriteta signala in zmanjšanje izgub kritična, presegajoč zmogljivost tanjših koaksialnih kablov v kompleksnih morskih okoljih.

« 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 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 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.

Frequently asked questions

Need help? Contact us

What is the characteristic impedance of this RG214/U coaxial cable?

The characteristic impedance of this RG214/U coaxial cable is 50 ± 2 Ω.

For which applications is the RG214/U coaxial cable designed?

The RG214/U coaxial cable is designed for demanding environments in marine radio, computer, and high-frequency systems. It is suitable for transmitting signals with high bandwidth and low attenuation, particularly for operating frequencies up to 11 GHz.

In which types of environments can I install this RG214/U cable?

This RG214/U cable is suitable for fixed or flexible installations in dry or wet environments. It withstands high thermal and chemical stress. It can also be used outdoors for fixed installations.

How is the shielding of the RG214/U coaxial cable structured?

The outer shielding of the RG214/U cable consists of a double braid made of silver-plated copper wires. It provides an inner coverage of 95% and an outer coverage of 98% (nominal value), ensuring excellent protection against electromagnetic interference.

What are the maximum frequencies supported by this RG214/U coaxial cable?

This RG214/U coaxial cable is specifically designed for operating frequencies up to 11 GHz. It allows signal propagation without distortion over short to medium distances.

What is the minimum bending radius for RG214/U coaxial cable?

The minimum bending radius depends on the type of installation, given that the outer diameter of the cable is 10.8 ± 0.18 mm:

For an occasionally mobile installation, the bending radius is 10 times the cable diameter. For a fixed installation, the bending radius is 6 times the cable diameter.
