Cable Construction

  1. Fluoropolymer Jacket (Tan)
  2. Tin-Plated Copper Braid Shield
  3. Aluminum Braid Shield
  4. Fluoropolymer Dielectric
  5. Tin-Plated Copper Conductor

Certain avionics systems — TCAS, TCAD®, IHAS, for example — specify a range of antenna cable insertion loss rather than a maximum loss. The loss minimum may be difficult to achieve in shorter cable lengths without coiling extra length of cable or inserting attenuators. Either situation adds weight and cost. This cable addresses these problems.

S46191 is a 50 ohm coaxial cable, dimensionally equivalent to M17/128-RG400, but whose loss is greater by approximately 8 dB per 100 feet at 1.0 GHz. RG400 is typically 15 dB;

S46191 is approximately 23 dB. In addition, S46191 will provide at least 40% weight savings over RG400.

A fluoropolymer jacket protects the cable against abrasion and environmental effects while maintaining flexibility for ease of installation.

It is Skydrol resistant, RoHS compliant and meets the FAA flammability requirements of FAR Part 23 and 25, Appendix F; complies with MIL-C-17 as applicable.
