Hard line
1-5/8" adjustable line
Hard bandage is acclimated in broadcasting as able-bodied as abounding added forms of radio communication. It is a coaxial cable complete application annular copper, argent or gold tubing or a aggregate of such metals as a shield. Some lower-quality harder bandage may use aluminum shielding, aluminum about is calmly breakable and clashing argent or gold oxide, aluminum oxide acutely loses able conductivity. Therefore all access accept to be air and baptize tight. The centermost aqueduct may abide of solid copper, or copper-plated aluminum. Since derma aftereffect is an affair with RF, chestnut plating provides acceptable apparent for an able conductor. Most varieties of hardline acclimated for alien anatomy or if apparent to the elements accept a PVC jacket; however, some centralized applications may omit the insulation jacket. Harder bandage can be actual thick, about at atomic a bisected inch or 13 mm and up to several times that, and has low accident even at top power. These all-embracing harder curve are about consistently acclimated in the affiliation amid a transmitter on the arena and the antenna or aeriform on a tower. Harder bandage may aswell be accepted by trademarked names such as Heliax (Andrew),32 or Cablewave (RFS/Cablewave).33 Larger varieties of hardline may accept a centermost aqueduct that is complete from either adamant or corrugated chestnut tubing. The dielectric in harder bandage may abide of polyethylene foam, air, or a pressurized gas such as nitrogen or anhydrous air (dried air). In gas-charged lines, harder plastics such as nylon are acclimated as spacers to abstracted the close and alien conductors. The accession of these gases into the dielectric amplitude reduces damp contamination, provides a abiding dielectric constant, and provides a bargain accident of centralized arcing. Gas-filled hardlines are usually acclimated on high-power RF transmitters such as television or radio broadcasting, aggressive transmitters, and high-power abecedarian radio applications but may aswell be acclimated on some analytical lower-power applications such as those in the bake bands. However, in the bake region, waveguide is added generally acclimated than harder bandage for transmitter-to-antenna, or antenna-to-receiver applications. The assorted bouncer acclimated in hardline aswell differ; some forms use adamant tubing, or pipe, others may use a corrugated tubing, which makes angle easier, as able-bodied as reduces kinking if the cable is angled to conform. Smaller varieties of harder bandage may be acclimated internally in some high-frequency applications, in accurate in accessories aural the bake range, to abate arrest amid stages of the device.
edit Radiating
Main article: Adulterated feeder
Radiating or adulterated cable is accession anatomy of coaxial cable which is complete in a agnate appearance to harder line, about it is complete with acquainted slots cut into the shield. These slots are acquainted to the specific RF amicableness of operation or acquainted to a specific radio abundance band. This blazon of cable is to accommodate a acquainted bi-directional "desired" arising aftereffect amid transmitter and receiver. It is generally acclimated in elevator shafts, US Navy Ships, underground busline tunnels and in added areas area an antenna is not feasible. One archetype of this blazon of cable is Radiax (Andrew).34
edit RG-6
Main article: RG-6
RG-6 is accessible in four altered types advised for assorted applications. "Plain" or "house" wire is advised for calm or alien abode wiring. "Flooded" cable is alloyed with abundant waterproofing for use in underground aqueduct (ideally) or absolute burial. "Messenger" may accommodate some waterproofing but is acclaimed by the accession of a animate agent wire forth its breadth to backpack the astriction complex in an aeriform bead from a account pole. "Plenum" wire comes with a appropriate Teflon alien anorak advised for use in blast ducts to accommodated blaze codes.
edit Triaxial cable
Main article: Triaxial cable
Triaxial cable or triax is coaxial cable with a third band of shielding, insulation and sheathing. The alien shield, which is earthed (grounded), protects the close absorber from electromagnetic arrest from alfresco sources.
edit Twin-axial cable
Main article: Twinaxial cabling
Twin-axial cable or twinax is a balanced, askance brace aural a annular shield. It allows a about absolute cogwheel arresting which is both cloistral and counterbalanced to canyon through. Multi-conductor coaxial cable is aswell sometimes used.
edit Biaxial cable
Main article: Twin-lead
Biaxial cable, biax or Twin-Lead is a figure-8 agreement of two 50 Ω coaxial cables, evidently akin that of lamp cord, or apostle wire. Biax is acclimated in some proprietary computer networks. Others may be accustomed with 75Ω biax which at one time was accepted on abounding cable TV services.
edit Semi-rigid
Semi-rigid cable is a coaxial anatomy application a solid chestnut alien sheath. This blazon of allure offers above screening compared to cables with a braided alien conductor, abnormally at college frequencies. The above disadvantage is that the cable, as its name implies, is not actual flexible, and is not advised to be channelled afterwards antecedent forming. (See "hard line")
Conformable cable is a adjustable reformable another to semi-rigid coaxial cable acclimated area adaptability is required. Conformable cable can be bare and formed by duke withouth the charge for specialist tools, agnate to accepted coaxial cable.
edit Adamant line
Rigid line
Rigid bandage is a coaxial bandage formed by two chestnut tubes accurate every added beat application PTFE-supports. Adamant curve are not accessible to bend, so they generally charge elbows. Alternation with adamant bandage is done with an close bullet/inner abutment and a border or affiliation kit. Adamant bandage is mainly acclimated central for alternation amid transmitters and added RF-components, but even added adamant adamant bandage with flanges is acclimated outdoors on antenna masts, etc. With a border adapter it is accessible to go from adamant bandage to harder line. Abounding broadcasting antennas and antenna splitters use the flanged adamant bandage interface even if abutting to adjustable coaxial cables and harder line.
