For

30m Ellipticus Antenna

S20-036

9 November 2020

PREPARED BY:

OC-ALC/OBCA

1. SCOPE

The Government requires the replacement of the Nuclear Testing Apparatus 20 meter Ellipticus Antenna located near Bldg. 1027 at Tinker Air Force Base (TAFB) with a new larger 30 meter Ellipticus Antenna. This shall include the replacement and removal of the existing antenna as well as all associated conduit supports and cabling.

2. BACKGROUND

TAFB is currently the only location with the technical expertise and equipment to conduct Nuclear Hardness testing for the Air Force. A new 30 meter extended antenna is required to support testing on various aircraft including the 747 E-4B, VC-25 and KC- 46A.

The 30-Meter Extended Ellipticus Antenna testing volume will provide sufficient area to accomplish Low Level Continuous Wave (LLCW) testing of a 747-200 airframe with the objective of testing a 747-8i.

3. REQUIREMENTS

3.1. Project Summary:

a) The Contractor shall dismantle and remove the existing 20-Meter Ellipticus

Antenna and Support System prior to starting any installation work. This shall include the antenna,the support system, both lower support poles, all guys and both support poles and the two (2) wooden poles from the older (and already dismantled) antenna.

b) The Contractor shall complete site preparation and foundation work, including support structure and winch foundations and pouring a concrete pad for the climate controlled, 8’ x10’ amplifier shelter.

c) Site preparation shall include preparation of the ground plane surface. Ground plane shall be leveled to approximate height of Compass Rose (Drawings Attachment #7). A concrete pad with wooden poles around the perimeter shall be installed to prevent damage to ground plane and pad.

d) The Contractor shall provide an 8’ x 10’ metal, climate controlled structure for the amplifier. It shall be placed on a pad and anchored in place at the base of the northwest antenna pole.

e) The Contractor shall provide power to the amplifier structure for lighting, climate control, additional 110 volt outlets, 220 volt 30 amp for the amplifier) and to the support structures (for the winches and emergency lighting system). This power to the shelter and northwest support pole shall be run from the existing service located in Building 1027 and the power to the southeast support pole shall be run from the existing southeast support pole. All power shall be run underground by the Contractor.

f) The Contractor shall erect the two support structures and hardware and secure with the Down-Guys and install the Cross-Guy between the two support structures. This shall be followed by installation of powered winches to raise/lower the antenna and lightning protection system. The antenna and ground plane shall then be installed. Once completed the Government will mount the Government furnished drive equipment in the portable amplifier shelter and install the antenna terminations.

g) Aircraft Warning Light System, Aerial Markers and Lightning Protection System shall be provided for the new Antenna and Supporting Shelter.

h) The antenna shall be capable of radiating a continuous wave electric field within the test volume of field strength of no less than 1V/m across the operational frequency range (10kHz to 1 GHz) when measured at a location 3 meters above the ground directly beneath the antenna balun. The antenna shall perform the requirement when driven with existing amplifier/network analyzer Microwave Instrumentation model SP1088 and Network Analyzer Keysight Technologies E5061B).

NOTE: This will be similar to a standard field mapping exercise performed routinely using the existing 20-Meter Ellipticus Antenna. See Figure 3.1 for explaination of process.

i) The Contractor shall develop and deliver a Validation Test Plan two weeks prior to the start of the Radio Frequency (RF) Validation Test for the Government to review. The Government will provide use of the Depot Hardness Surveillance Test System (DHSTS), instrumentation and drive system to support the RF Validation Test. The Government will conduct an RF Validation Test on the 30- Meter Extended Ellipticus Antenna after installation to verify its functionality and that it meets all illumination requirements. The Contractor shall be present during this test, to observe testing to ensure that there are no conflicts with results produced from this testing. Following the validation testing, the Government will provide the test results to the Contractor, however the contractor shall be responsible for generating and delivering a RF Validation Test Report. The Test Report shall provide a comparison of measurements derived from computational electromagnetics modeling and simulations with RF Validation test results for locations as identified in Figure 3-1:

j) The Contractor shall leave the area clean and without debris.

k) A Project schedule for all project activities will be provided as part of the

Contractor’s initial quote with the final approved schedule provided to the Government POC 30 days after contract award.

l) The contractor shall provide monthly progress updates to the Government via email. These updates shall reference the Project schedule and provide an overall status of Ontime No Constraints, Ontime with Constraints, Ahead of schedule, or Behind schedule. In addition to overall status the Contractor shall annotate items completed, items being worked, and projected time of start for all other items.

The following shall be used to determine what additional information is required.

Ontime No Constraints – All projected dates from original approved schedule are on track and no constraints for completion have been identified.

Ontime with Constraints – All projected dates from original approved schedule are on track, but there are constraints or the potential for constraints. This status shall include a listing of constraints as well as what steps are being done to correct the issues.

Ahead of Schedule – One or more individual dates for completion of steps are ahead of schedule with the potential for early completion of the overall project. This shall identify the steps ahead of schedule with an estimation of a new completion date. This is just an estimation for internal use only and will not change the completion date assigned at time of contract award.

Behind Schedule – One or more individual dates for completion of steps are behind schedule with the potential for late completion of the overall effort. This shall identify the steps behind schedule with an estimation of a new completion date for those steps as well as a new estimation for completion of the overall project. This shall also include the reasons for the delay in detail. The contractor shall provide an assessment for review on possible solutions to reduce/remove the delay or provide a determination as to why there is no path to remove or reduce this delay. A copy of all details will be sent to the Contracting Officer for review and determination.

m) The Contractor shall provide As-Built Drawings and .dwg files before project close out for Government POC review and master file updates.

n) The Contractor shall provide Antenna and Support System Operation and Maintenance (O&M) Manual
