AUDIO WIRELESS LPDA-WB-A

The LPDA-A-WB may be used in an active or passive mode to suit individual applications:

• active mode with fixed bandwidth in the 470-700 MHz range with user adjustable gain of 18dB
• passive mode (when there is no dc present) can be used as a high gain
• passive antenna to receive or to transmit with the in-built filtering 470-700 MHz, passive gain boasting 5dB.

This unique design has an exceptionally low loss and a very selective band-pass filter with fixed bandwidth between 470-700 MHz. The booster section uses a digitally adjustable RF-Attenuator before the low noise RF Amplifier against RF overload and the Booster Gain adjust is after the RF amplification, both digitally adjustable RF-Attenuators are independently user adjustable in 1dB steps. The RF amplifier is an extremely high dynamic range and low noise RF amplifier offering a linear gain within the tuning range.

The LPDA-A-WB offers flexibility as well as additional front-end protection against interfering dirty RF, the booster offers 18dB user adjustable gain to compensate long antenna extension cable losses hence increased distance between the transmitter and the receiver, LPDA-A-WB finds its application in film making, documentaries, fixed installations as in studios, and theatres. Compatible with any UHF wireless receiving systems (digital or analogue) providing a directional coverage pattern.

The antennae are 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 it can be mounted directly on to a microphone stand. Powering is through coaxial cable, power source of 10-18Vdc.
