About this file
This document is a Questions and Answers (Q&A) file for the HNAE Tower Re-Cabling Infrastructure project at Hanscom Air Force Base. The opportunity involves removing old cabling and installing new Radio Frequency (RF) cabling on a 120-foot composite tower located at 15 Eglin Street, Building 1607. Key details from the Q&A include confirmation of a climbing ladder, existing 3/8" tower safety climb cable system, and specific requirements such as using only plastic cable blocks for supports. The project requires new cable supports, ground kits (minimum 3 per cable), and addresses technical specifications for two antenna types with frequency ranges of 125-3000 MHz and 950-2000 MHz. While no specific cost estimate was provided, the start date is set for the time of award, and the cable replacement will extend from the antenna to the rooftop doghouse. The solicitation is issued by the Department of the Air Force Materiel Command Lifecycle Management Center at Hanscom Air Force Base, with the solicitation number 2025-PZI-1481.

Q&A
| Questions: | Answers: |
| NOTE: ALL PICTURES TAKEN FROM THE SITE VISIT HAVE BEEN POSTED IN ATTACHMENT 1 | |
| Is this composite tower man-rated? | YES |
| Does it have step pegs or a climbing ladder? | CLIMBING LADDER |
| Does it have a functional tower safety climb cable system on it? | YES, 3/8" CABLE |
| Can the Government provide any pictures taken from the ground showing the overall tower? | Please see picture labeled "DSC_1425" and "DSC_1454" in attachment 1. |
| Can the Government provide photos of the rooftop entry box showing the surge arresters? | Please see picture labeled "DSC_1455" in attachment 1. These are attached to the box utilizing the hexnut. Location is shown on picture "DSC_1426" in Attachment 1. |
| Do the connectors attaching to the bottom surge arresters need to be right angle connectors? | No |
| Can the existing cable supports be re-used? | NEW CABLE SUPPORTS REQUIRED |
| Are there ground kits that need to be installed on each cable since this is a composite tower? If so, how many for each cable? Typically, there would be a minimum of 3 per cable for these lower centerlines. | Yes- Please provide your proposed solution in your response |
| Is the cable tray running up the tower made of composite or aluminum, and does it have a lid fastened down with screws? | COMPOSITE, NO LID |
| In the requirements section of the SOW, it states that the contractor will provide a dehydrator for the coaxial or Heliax cables. Is there currently a dehydrator being used with the existing coaxial cables? | We do not currently have one. What we are looking for is a way to prevent water intrusion into the cables- If there is a better method, please provide the proposed solution in your response |
| If we need to provide cable supports, can they be stainless steel or do they need to be supports utilized with PIM mitigation? | Only plastic cable blocks. |
| Can the Government provide the make and model of the 2 antenna types or can the frequency ranges of the antennas be provided? | The Discone antennas are 125-3000MHz, the other antennas are 950-2000 MHz |
| Is there a cost estimate , budget or ballpark figure for the project listed? Is there an actual start date for the project? | This is a commercial service. There is not a cost estimate to be released. The start date is at time of award. |
| Can you please provide the total length of each cable run that is needing replaced from the antenna on the tower to the radio location? | The cable replacement will be from the antenna to the doghouse on the roof. Those cable lengths are in the SOW |
| The project scope mentions the use of a dehydrator for the lines, these cables unless otherwise specified are coaxial foam and therefore would not need dehydration. Confirming we will not be providing a new dehydrator for the new coaxial cabling supplied. | We do not currently have one. What we are looking for is a way to prevent water intrusion into the cables- If there is a better method, please provide the proposed solution in your response |
