Patch Panels - Rapid Release U Links

Rapid release U links provide manual switching for high power RF circuits. Typical applications include transmitter, antenna and test load patching. Manufactured in custom built configurations ranging from simple patch panels to fully integrated multichannel switching. Features include:

  • Fast, simple lever action
  • Slimline - low profile design
  • Interlock circuits operate before the RF circuit is disturbed
  • Available in five sizes to match RFS rigid line sizes/power ratings
  • Standard EIA or IEC test adapters can be used
  • Input/output line sizes can be varied to suit using RFS developed R series adapters

Broadcast Rigid Line

RFS produces a range of 50 ohm rigid line components. Items for both unpressurized (indoor) systems and pressurized, flanged (outdoor) systems are available in 7/8", 1 5/8", 3 1/8", 4 1/2", 4 7/8" and 6 1/8" sizes. All components are manufactured to the most exacting tolerances. Features include:

  • High Conductivity Copper Lines: Line inner and outer tubing is of high conductivity, hard-drawn, copper, milled to exact dimensions. Unflanged components for indoor use are polished and sprayed with a clear lacquer to maintain a high luster finish
  • Welded Construction: Flanges and mitered elbow joints are TIG welded for maximum strength
  • Low Loss PTFE Dielectric: Captive PTFE dielectric insulators are used exclusively in lines and elbows to ensure precision mating and stability of components after assembly
  • Silver Plated Contacts: All inner conductor connectors are silver plated
  • Standard Sizes: All components conform to the relevant EIA or IEC standards

Air Coaxial Cable

air dielectric cables consist of an inner conductor and an outer conductor. By using a dielectric helix (made of high density polyethylene) the inner conductor is centered to the outer conductor. The shape of the dielectric is either rectangular or in the case of small diameter cables, trapezoidal. Larger cables use a low material content helix with T-shaped supports. Cables for the highest power transmission use three-legged Teflon spacers, which are positioned periodically along the cable. All HELIFLEX air dielectric cables are designed to incorporate the following features:

  • High flexibility
  • High crush resistance
  • Low attenuation
  • High power rating
  • Longitudinal uniformity

HELIFLEX® cables are designed for applications where high flexibility and crush resistance are required. The attenuation of HELIFLEX® cables is much lower when compared to the foam dielectric cables. HELIFLEX® cables are used extensively worldwide for the transmission of large RF power.

  • Feeder cables for broadcast stations
  • AM / FM
  • Analog and digital TV
  • MDS / MMDS

Broadcast Filters

RFS bandpass filters are primarily used as part of multichannel combiner facilities but can also be used to eliminate spurious emissions and increase isolation between co-sited services.

Pressurization Equipment

Elliptical waveguide, air dielectric coaxial and rigid line should be pressurized with dry air or dry inert gas in order to prevent moisture condensation and the resultant degradation in electrical performance and possible damage to the transmission line. Radio Frequency Systems offers a comprehensive range of dehydration systems designed to meet both the technical and economic needs of our global customers.
