Description
N280-04F Adaptor Female to Male
The N280-04F Adaptor Female to Male is a chrome plated brass marine antenna thread adaptor designed to convert a 1″-14 TPI female thread to an ISO 228/1-G1 male thread. It is useful where existing antenna mounts, fabricated brackets or vessel hardware use a different thread standard to the antenna or mounting component being installed.
Key Functions
Why Use the N280-04F?
Marine antenna installations often involve existing mounts, welded brackets or fabricated antenna supports that use different thread standards. The N280-04F allows installers to convert between 1″-14 TPI and ISO 228/1-G1 threads without replacing the full mounting arrangement.
Common Uses for the N280-04F Adaptor
Used where an antenna or mount requires conversion between 1″-14 TPI and ISO 228/1-G1 thread standards.
Provides a practical thread conversion solution when combining different AC Antennas mounting components.
Useful where vessel owners, yards or fabricators have welded custom antenna brackets with a thread size that does not match the replacement antenna hardware.
On commercial fishing vessels, workboats, pilot boats, offshore support vessels and leisure craft, it is common to find existing antenna brackets or welded mounts that do not match the thread standard of the new antenna system. The N280-04F provides a practical way to adapt the installation without unnecessary fabrication work.
Typical Applications
Suitable for marine antenna mount conversions, VHF antenna installations, AIS antenna systems, cellular antenna mounting and AC Antennas hardware setups using the N239F revolving nut.
