General description

The High Frequency Global Communications System (HFGCS) System Program Office (SPO) is responsible for the sustainment of the HFGCS system. HFGCS is the ground based global high-powered, high frequency communication backbone that provides both Primary and Secondary Line-of-Sight communications to the joint war fighter

The HFGCS system consists of two sub components, one being the radio system and the second being the antenna system. The antenna system is composed of over three hundred antennas spread across 26 sites around the world consisting of many different makes and models. One model, the TCI 521 Rotatable Log Periodic (RLP) currently fielded has a controller that acts as the interface between radio system software and the physical antenna which enables the antenna to be rotated to different azimuths by the radio operator.

Currently two TCI 521 RLP antennas in the field are non-operational due to bad controllers and no functional spares available.

The purpose of this document is to inform the Contractor what our objectives are, with the expectation that the Contractor can better define what and how the work should be done in order to meet those objectives

1. SCOPE: The scope consists of evaluation and repair of four (4) RLP controllers

2. Program Objectives: The Contractor shall provide the support necessary for the accomplishment of these specific objectives on 4 TCI 521 Controllers (P/N 2724-

ASY-02A):

2.1. Inspection, Diagnosis and if feasible perform minor repairs to bring the TCI 521 RLP Controllers to an operational status.

2.2. If major issues are identified provide a cost of estimate.

2.3. If needed repairable parts are not available based upon obsolescence issues provide a list of these parts.

3. Test and Evaluation Objective: Diagnostic Testing associated with a bench type mockup of the TCI 521 RLP Antenna and Controller will be performed to validate the operational status of the Controller.

4. Logistical Support Objective: The Contractor shall establish/maintain procedures for handling, storage, preservation, packaging, and shipping to protect the quality of products and prevent damage, loss, deterioration, degradation or substitution of products.

5. Schedule: Upon receipt of each unit, fastest turnaround time is anticipated.
