Frequently Asked Questions
What is a shutter antenna bracket?
A shutter bracket (GMF4x4 "SB" prefix) is designed to mount an antenna at the vehicle's window or cargo area shutter — the roll-up or hinged panel used to secure the vehicle's cargo space or side access. This is a different mounting location from a bonnet bracket (GMF4x4 "BB" prefix) or tailgate/boot bracket (GMF4x4 "TG" prefix). Shutter brackets are commonly used on commercial, service, and utility vehicles where other mounting positions are not accessible or practical.
What does "HSP Series 3" refer to?
The specific vehicle or platform designated as "HSP Series 3" is not defined in the available supplier data. Confirm with GMF4x4 or your supplier exactly which vehicle this SKU is designed for before purchasing.
What does M6 mean for the antenna thread?
M6 refers to the antenna mount thread specification — a 6mm metric thread. This is one of the standard thread sizes used on UHF CB antenna bases. Ensure the UHF antenna you intend to mount uses an M6 male thread base before purchasing. Other common sizes include M5 and ¾-24 UNF — these are not compatible with this bracket without an adaptor.
Is the antenna included?
No — the SB-039-BLK is a mounting bracket only. A compatible M6-thread UHF antenna, antenna cable, and UHF CB radio are required separately.
Is there a natural finish or other colour option available?
The "BLK" suffix in this SKU denotes the black powder coat variant. A natural or polished finish version may exist in the GMF4x4 range under a different SKU — confirm available colour options with your supplier.
