GP4 short-wave 4-band 1/4-wavelength GP antenna, working frequency 7, 14, 21, 28/29M, quick-install GP antenna, suitable for long-term use outdoors and on the roof! No need to replace the coil to switch the frequency. Basic parameters: Antenna 5.65 meters, weight 2.3 kg, wind resistance level 12, power PEP1000W, exquisite notch technology, superior electrical structure performance, is a high-efficiency GP antenna.
      The ground net is simple to lay, and the fan-shaped flat ground (more than 7 ground nets, reference length 2.5 meters*, 5 meters*) is enough. In principle, the more ground nets, the better. The recommended installation height is 0.3-0.5 meters, equipped with a dedicated mounting plate. 
 
        GP4 can also be installed horizontally on the balcony to become a balcony antenna. The metal guardrail is used as a ground net (this antenna requires a counter poise which is not included)
