The LPDA-A-DB Dual-Band Active Log Periodic Dipole Array antenna is designed to operate over the 470-1164 MHz range. It consists of two sections: a passive antenna and an active dual-band band-pass filter antenna with booster. The user selectable front-end filtering determines the operating frequency range of the LPDA-A-DB. The dual-band LPDA-A-DB may be used in ACTIVE or PASSIVE mode to suit individual applications: PASSIVE MODE (when there is no DC power present) can be used as a high gain passive antenna to receive or to transmit with passive 5dB gain ACTIVE MODE (when DC powered through the coax-cable): MODE 1: user selectable 470-700 MHz ONLY (lower end can be custom tuned between 470/510/520MHz at the time of order) MODE 2: user selectable 960-1164 MHz ONLY MODE 3: both ''band-pass filters'' ON at the same time (excellent "band rejection" between 700 MHz and 960 MHz) This unique design has an exceptionally low loss and a very selective front-end band-pass filters with fixed bandwidth between 470-700 MHz and 960-1164 MHz. The RF amplifiers offer a high dynamic range, very low noise and linear gain within the tuning range. The LPDA-A-DB offers flexibility as well as additional front-end protection against interfering dirty RF, the booster offers 20dB user adjustable gain to compensate long antenna extension cable losses hence increased distance between the transmitter and the receiver, LPDA-A-DB finds its application in film making, documentaries, fixed installations as in studios, and theatres. Compatible with any UHF wireless receiving systems (Digital, Digital hybrid or Analogue) providing a directional coverage pattern. The antenna is constructed using advanced multi-layer PCB design technique with copper-clad epoxy fiberglass to withstand heavy duty use in harsh environments, providing long life and consistent performance under difficult operating conditions. The booster box is a custom-design machined aluminum, black anodized with water resistant O-ring mounting. Mounting is made easy with integrated thread that directly mounts on to a tripod or with the supplied adaptor can be mounted directly on to a microphone stand. Powering is through coaxial cable, power source of 10-18Vdc.
