Audio Wireless LPDA-A-DT V2 Narrow-Band Digitally Tuned LPDA Antenna

The Audio Wireless LPDA-A-DT V2 is a narrow-band digitally tuned LPDA antenna that pairs a passive log periodic section with a booster module. The module’s filter tunes to a 24 MHz window anywhere from 470 to 702 MHz.

Rejecting everything outside that window protects the receivers when the spectrum is crowded. You set the mode from the OLED menu. Digitally Tuned mode moves the filter in 8 MHz steps and adds up to 20 dB of gain. Wide-Band mode opens a fixed, low-loss filter across 470 to 702 MHz with up to 14 dB of gain. With no DC on the coax, the antenna runs passively for receive or transmit, with its built-in band-pass filter and 5 dB of gain.

A digitally adjustable attenuator at the input guards against RF overload, and a separate booster gain control makes up for loss in long antenna cables. The antenna works with any UHF wireless receiving system, digital or analog, and has a directional coverage pattern.

The elements are multi-layer PCB in copper-clad epoxy fiberglass, built for heavy use in harsh conditions. The booster is a black anodized, CNC-machined aluminum box with water-resistant O-ring mounting. An integrated thread mounts the antenna directly on a tripod, and the supplied adapter fits a microphone stand. Power is 10 to 18 V DC through the coax.
