Harbour Braided Wire Separator

Harbour Industries is the leading supplier of QPL approved MIL-DTL-17 cables. All 50 Ohm constructions are swept for VSWR to ensure product quality. To meet demanding customer requirements, Harbour manufactures special versions of MIL-DTL-17 cables. Harbour's MIL-DTL-17 cables are used in wireless and cellular communication systems and antenna systems around the world.

Harbour also manufactures special RF Microwave cables used for numerous military and commercial aerospace applications, radio communication systems, internal RF transmission lines, and antenna distribution systems. These special series of cables include LL Low Loss coax with high velocity PTFE dielectrics and composite shields for high frequency and high power applications. Flat strip braids are also used in Harbour's SB Coax series, and spiral shields are used in Harbour's SS Coax series.

Attenuation Calculator

Although typical and maximum attenuation values at discrete frequencies may be found in Harbour's online catalog, this Attenuator Calculator makes it easy to compare multiple items at any operating frequency. Just type a frequency in MHz (for instance 18 GHz = 18,000 MHz) to calculate and compare typical attenuation values.
