A Central Link for Professional HF Configurations in VHF and UHF
Designed to integrate naturally into a professional HF receiver setup, this multiband active antenna distributor simplifies installations where multiple receivers need to share the same antennas. Instead of multiplying antennas (and increasing risks of interference, confusing wiring, or inconsistent RF levels), it centralizes signal distribution and serves as a key element in a reliable HF chain, especially alongside the QLXD, ULXD, and UR series.
Who Is It For and What Are Its Uses?
This antenna distributor is intended for sound contractors, stage managers, fixed installations (theaters, conference rooms, places of worship), and event environments that operate multiple HF channels simultaneously. It is particularly relevant when you need to secure RF reception, save setup time, and maintain a clear infrastructure (antennas mounted high, receivers in the control room, controlled cable lengths).
It is also well suited for hybrid configurations where receivers operate on different bands: the front panel selector allows quick adaptation of the device to the working band without complicating your rack or changing accessories.
Questions frequently asked
Is the Shure UA845UWB-e compatible with QLXD and ULXD receivers?
All four 15 V DC outputs can power single QLXD4E or ULXD4E receivers, with a maximum current of 2.5 A. The necessary power cabling for the mentioned receivers is provided.
Which frequency bands are supported?
The front panel selection covers the ranges 174 to 216 MHz, 470 to 960 MHz, and 1785 to 1805 MHz. The bands 1240 to 1260 MHz and 1492 to 1525 MHz are also present. These last two are not usable in France.
How many wireless receivers can be connected to the distributor?
Each antenna has 4 RF outputs to connect multiple receivers to the same antenna pair. A daisy-chain port allows connection of a fifth receiver or chaining another distributor.
Can active antennas be powered with this distributor?
The active antenna power supply provides 12 V DC, with a maximum current of 300 mA.
How to identify RF overload on the UA845UWB-e?
Two front panel LEDs light up in case of RF overload. This indication allows quick identification of excessive RF levels caused, for example, by antenna placement or a congested environment.
