Special Features

  • 【4-Band High Efficiency DXing】 Operate seamlessly across 7MHz, 14MHz, 21MHz, and 28/29MHz (40m/20m/15m/10m) bands. This high-performance HF vertical antenna utilizes precise notch filters, eliminating the need for manual coil changes during frequency switching
  • 【1000W PEP High Power Handling】 Engineered for amateur radio enthusiasts of all levels, this base station antenna easily handles up to 1000W PEP. Whether participating in contests or regular global DX communication, it delivers a stable, strong, and clear signal
  • 【Grade 12 Wind Resistance & Durable】 Constructed from lightweight yet heavy-duty aluminum weighing just 5 lbs (2.3kg), it survives severe weather and strong winds. Ideal for long-term outdoor setups in your backyard, flat rooftop, or mounted on open-sky balcony railings
  • 【Radial-Based SWR Tuning】 This 1/4 wave ground plane antenna requires external radial wires (not included) to operate. SWR (<1.5) matching is effortlessly achieved by trimming the lengths of the ground radials (5m for 40m, 2.5m for upper bands) rather than adjusting the main antenna body
  • 【Easy Base Station Setup】 Designed with a dedicated mounting plate for a recommended installation height of 1 to 1.5 ft (0.3-0.5m) above ground. Unlike horizontal wire antennas that require over 60 ft of clear aerial space, this vertical layout with flexible ground routing saves significant yard space, making it an excellent primary shortwave radiator for restricted urban areas.
  • 【Radial Wire SWR Tuning】: Operates as a quarter wave system requiring user supplied ground wires,Attains optimal impedance matching by trimming radial lengths,Protects the main radiator factory calibration by avoiding tube cutting

Description

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 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.
