Product information

The A1031-U from Sennheiser is a wideband UHF antenna with an omni-directional pickup pattern. This is designed fo use with the Sennheiser Evolution series of wireless microphones although it can be used with other systems.
While the short antennas that come supplied with radio microphone systems are pretty good they don't always offer the best performance. Good signal reception is a key factor to minimising RF problems. Ideally you want the receiver antennas as close to the transmitters as possible and with clear line of sight. When the antennas are located directly on the receiver these factors are often compromised. By using an A1031U remote antenna, you can keep the antenna in clear line of sight and simply connect the antenna to the receiver using some low-loss RF cable. Additionally, the larger surface area of the antenna provides a higher output level for the RF signal - helping to compensate for losses incurred over distance.

The antennas themselves have an integrated bracket with a standard microphone stand threaded insert. Simply screw the antenna onto a mic stand to enable clear line-of-sight. Additionally, as these antennas have an omni-directional pickup pattern, they don't have to be oriented in any particuar way and are particularly use in situations where the transmitters will move over a wide area, such as promenade performance.

And don't compromise on the RF interconnect cables. Often people us the cheapest RG58c/u cable type. This type of cable has quite a high loss and so is only really recommended for short links. We recommend using RG8-X cable which offers a much lower loss over distance while still remaining quite flexible.
