Dual-Band Active Log Periodic Dipole Array antenna LPDA-A-DB is designed to
operate over the 470-1164MHz range, the LPDA-A-DB consisting of two
sections: LPDA-P passive antenna and an Active Dual-Band, Band-Pass Filter
Antenna Booster sections, 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:
Active Mode (when powered through the coax-cable)
MODE 1: User selectable 470-700MHz ONLY (lower end can be custom tuned between 470/510/520MHz-to order)
MODE 2: User selectable 960-1164MHz ONLY
MODE 3: Both “Band-Pass Filters” ON at the same time (excellent “Band Rejection” between 700MHz and 960MHz)
Passive Mode (when there is no dc present) can be used as a High Gain Passive
antenna to receive or to transmit with passive 5dB Gain
This unique design has an exceptionally low loss and a very selective front-end Band-pass filters with fixed bandwidth between 470-700MHz and 960-1164MHz. The RF Amplifiers offers 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 antennae 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.KEY FEATURES:
- Active Dual-Band LPDA with 20dB gain
- Dual-Bands in the 470-700MHz and 960-1164MHz (UK DME Band)
- May be used as an Active, Passive Receive or Transmit
- No dc- Passive Mode with ultra-wide band 470-1525MHz
- Extremely high dynamic range RF amplifiers
- Input high selective Band Pass filtering
- User adjustable Booster Gain in 1dB steps
- Intuitive OLED display menu
- Powered through coax cable
- Integrated mount adaptor
- CNC machined custom design
