Preliminary A. Trim coax outer insulation back 0.50”. B. Trim braid (not center conductor or insulation) back 0.25”. C. Strip Insulation back 0.120”. NOTE Place the ferrule over the coax braid, flush against the coax outer insulation before performing the next step if the outside diameter of the coax braid is smaller than the inside diameter of the center connector sidewall opening. D.
Preliminary 2.4 GTX 327 INSTALLATION NOTES Avoid installing the unit near heat sources. If this is not possible, ensure that additional cooling is provided. Allow adequate space for installation of cables and connectors. The installer will supply and fabricate all of the cables. All wiring must be in accordance with FAA AC 43.13-2A. 2.5 A.
