Three documented operating bands
GL-DY7040V11 is a vertically polarized log-periodic antenna. Its source lists three operating ranges: 698–960, 1710–2700 and 3400–4000 MHz, with gain values of 10 / 10.5 / 11 dBi. The intervals between those ranges are not specified as operating bands.
The documented input connector is N-K. Pole-holding hardware fits a 35–60 mm diameter pole. The antenna measures 440 × 210 × 65 mm and weighs 1.2 kg. Check the mating connector and installation clearance against the project hardware.
The source lists VSWR ≤1.8, 50 Ω input impedance, 50 W maximum input power and DC-ground lightning protection. IM3 is ≤−150 dBc under a 2 × 33 dBm test condition. Operating temperature is −40°C to +65°C, and rated wind velocity is 60 m/s. Confirm the gain requirement for each selected band with the RF team.
