HLP-4 4m Halo Loop Folded Dipole Antenna 70–71MHz, 200W

The Moonraker HLP-4 is a compact halo loop folded dipole antenna designed for the 4m amateur band (70–71 MHz). Its square halo form factor measures just 600mm across, making it one of the most space-efficient options for 4m operation — well suited to loft installations, portable setups, or any location where a full-size dipole isn’t practical.

Omni-directional coverage with unity gain ensures consistent horizontal radiation in all directions, while the direct dipole centre connection keeps the feed arrangement clean and straightforward. VSWR of 1.5:1 or better and a 200W power rating make it a reliable choice for SSB and FM operation on the 4m band.
