Five Mistakes to Avoid When Using Wireless

While wireless systems have freed performers from the bonds of cords and cables, they've unleashed a number of headaches for the sound crew. Getting a wireless system to behave predictably is a challenge faced by touring prof...

Remote Antennas for UHF-R, BLX4R, SLX, ULX, QLX-D or ULX-D Receivers

Remote Antennas for UHF Wireless Microphones Click here for an online remote antenna tool. Antennas are described in terms of the signal wavelength they are designed to pick up. The antenna supplied with Shure...

RF signal loss in cable runs - impedance or cable length?

RF signal loss due to the length of the cable run is far more significant than loss due to an impedance mismatch. Using a 100 foot run of 75 ohm antenna cable with low loss is better than using a 100 foot run of 50 ohm antenna ca...

ULXD Antenna Cascade

The recommendation is two units.  This applies to the ULXD dual receiver (ULXD4D) and the ULXD quad receiver (ULXD4Q).  The antennas connect into receiver unit #1 and cascade into receiver unit #2. The cascaded uni...

How to calculate RF signal loss in coaxial antenna cable

Indeed it is important. Shure has a remote antenna tool to help determine which cables and amplifiers to use at: Wireless Mic Remote Antenna Tool Here is an online calculator for cable loss:

QLX-D Antenna Distribution

It is the same as with ULX-D single receivers.  Use the UA844+SWB RF distribution amplifier, UA221 RF splitter/combiner, etc. See our online Wireless Accessory Wizard. Note: Unlike the ULXD4, the QLXD4 does NOT provide ...

Collection of Wireless Troubleshooting Links

Wireless troubleshooting is difficult when on site. Via telephone, it is even more difficult. Via email or chat, it is nearly impossible. The root issue is that there are multiple variables which affect wireless microphone instal...

Antenna Types

The size of an antenna is directly related to the wavelength of the frequency to be received. The most common types used in wireless audio systems are 1/4-wave and 1/2-wave omni-directional antennas, and unidirectional antennas. ...

Antenna Distribution - 2 rooms, 4 antennas

For multiple room coverage, use passive combiners. Since they do not require power and are typically compact, they can be located wherever necessary. A passive combiner will typically result in at least 3 dB of loss, so be sure t...

Outdoor antenna for UHF wireless systems

Yes, there are outdoor weather resistant antenna that may be used for UHF wireless microphone systems: Winegard and others makes outdoor antennas suitable for the 470-698 MHz range. One example that Shure has tested with goo...
