WOOKLEA GP4 HF Trap Vertical Antenna 4 Band 7 14 21 29MHz, Shortwave Ground Plane Radiator 1000W PEP, UHF Female Connector, for Amateur Radio DXing and Open Air Urban Setup

WOOKLEA GP4 TRAP VERTICAL ANTENNA: MAXIMUM DX IN MINIMUM SPACE Don't let urban living or restricted yard space restrict your global communications. The WOOKLEA GP4 is a heavy-duty, space-saving HF base station antenna designed for dedicated ham operators and survivalists who need reliable 4-band coverage (7/14/21/29MHz) without the massive footprint of horizontal wire dipoles. ADVANCED TRAP TECHNOLOGY The secret to its sleek profile is the highly machined notch filters integrated into the vertical aluminum mast. These traps automatically block or pass specific RF frequencies, allowing the antenna to physically remain at 18.5 ft while electrically resonating on the 40m, 20m, 15m, and 10m bands. THE URBAN MOUNTING ADVANTAGE While horizontal antennas require over 60 ft of clear aerial space, the GP4 vertical radiator focuses its footprint on the ground. Install it on a flat rooftop, a compact backyard, or securely mount it on an open-sky apartment balcony bracket (minimum 18.5 ft vertical clearance required). HEAVY-DUTY 1000W PEP PERFORMANCE Despite its manageable 5 lbs weight, this antenna is a beast. It easily handles 1000W PEP amplifiers and is structurally rated for Grade 12 wind resistance to survive severe storms and field day conditions.

CRITICAL INSTALLATION & TUNING NOTES: RADIALS
REQUIRED: This ground plane antenna will not work without radial wires (not included).
TUNING THE SWR: Achieve a perfect < 1.5 SWR exclusively by trimming your radial wires. NEVER alter the length of the main antenna tubes!
TUBE JOINTS & SECURE FASTENING: The pre-drilled holes are for factory alignment. Secure the joints with the included screws for a reliable, removable assembly, or apply the provided pop rivets for permanent, deep reinforcement if installing long-term in stormy environments. Take command of the HF bands with a rugged, no-tune base station solution.
