Detailed description

Mõeldud raadio-, arvuti- ja kõrgsagedussüsteemide rangedes tingimustes kasutamiseks merepinnal, tagab koaksiaalkaabel RG214/U signaalide edastamise kõrge ribalaiusega ja madala sumbumisega. See kaabel on välja töötatud töösagedustele kuni 11 GHz, võimaldades signaalide moonutuseta edastamist lühikestel kuni keskmistel kaugustel.

Konstruktsioon ja tehnilised omadused

RG214/U vastab MIL-C-17 standarditele M17/75-RG214, MIL-DTL-17 H: M17/190-00001. Sisejuhtmeks on 7x0,76 mm (3,17 mm²) hõbenatud vasklits, mille läbimõõt on umbes 2,3 mm. Isolatsiooniks on PE, läbimõõduga 7,25 mm. Välisvarjestus koosneb topelt hõbenatud vasktraadist punumisest, mille sisemine katvus on 95 % ja väline 98 % (nimetatud väärtus), pakkudes suurepärast kaitset elektromagnetilise interferentsi vastu. Kaabli välisdiameeter on 10,8 ± 0,18 mm, musta PVC-kattega.

RG214/U elektrilised omadused 20°C juures: iseloomulik impedants 50 ± 2 Ω, maksimaalne töömahtuvus 101 pF/m 1 kHz juures. Sumbumine on kontrollitud, maksimaalsed väärtused: 10 dB/100 m 200 MHz juures, 28 dB/100 m 1000 MHz juures ja 197 dB/100 m 11000 MHz juures. Levimiskiirus on 0,66 c. Kaabel talub tippinge 5,0 kV (HF) ja nimipinget 3,7 kV (efektiivne), testimispinge 10 kV AC.

Kasutusvaldkonnad ja paigaldus

RG214/U sobib nii püsiasenduste kui ka paindlike paigalduste jaoks kuivades või märjades tingimustes ning talub kõrgeid termilisi ja keemilisi koormusi. Välispaigaldusteks püsiasendustes on see sobiv. Tulekindlus vastab IEC 60332-1-2 standardile. Kaabel vastab direktiivile EU 2011/65/EU (RoHS). Võrdluseks: vähem nõudlike rakenduste jaoks kasutatakse tihti RG58, kuid RG214/U topeltvarjestusega ja kõrgsagedusliku töö võimendusega on lahenduseks kohtades, kus signaali terviklikkus ja kadude vähendamine on kriitilised, ületades peenemate koaksiaalkaablite jõudluse keerukates mereoludes.

« RG214/U: The Technical Choice for 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 critical. 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 a budget 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 stresses. 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 bend radius for RG214/U coaxial cable?

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

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