What is reciprocity?

Reciprocity is a property of all antennas. Polarization, gain, bandwidth, and frequency response are the same whether an antenna is receiving or transmitting a RF signal.

What is circular polarization, in reference to the Helical Antenna?

Most commonly used antennas in wireless audio are linear polarized. Linear polarization means that the antenna is radiating electromagnetic energy on one plane only, either vertically or horizontally. For maximum signal strength, both the transmit and receive antennas in a wireless system must be oriented in parallel with each other. Any deviation from this position will result in signal loss, with a perpendicular antenna orientation creating the maximum amount of degradation. A performer using a wireless in-ear receiver and microphone transmitter rarely ever stays completely still. This constantly changes the antenna polarization, weakening the RF signal.

With circular polarized antennas, such as the PWS Helical and Domed Helical, the electromagnetic field rotates in a circular motion for every RF frequency cycle. This means that no matter how the transmit and receive antennas are oriented in reference to each other, the signal strength remains constant.

What is the difference between a right hand and left hand Helical Antenna?

Helical antennas are circularly polarized. The electromagnetic wave from a right hand Helical rotates clockwise in the direction of the wave’s propagation. This is known as right hand circular polarization. Left hand circular polarization is when the rotation of the electromagnetic wave is counter clockwise. As a standard, the copper element on the PWS Helical Antenna is wound with a right-hand polarization.

What in-ear monitor transmitters can be powered using the GX power output option?

The GX power option has jumpers with barrel-type plugs that will provide AC power for Sennheiser G2 and G3 series in-ear monitor transmitters. With this option, the GX-4P will power up to four units. The Dual GX-4P and GX-8P can power up to eight units each. Although the combiner function of the GX series can be used with any transmitter in the 470 – 699 MHz range, no transmitters other than Sennheiser G2 and G3 series are supported by the GX power output option.

I need to move my copy of IAS to a new computer. How do I go about transferring the software license?

IAS license transfers are processed manually. Please send an email to support@professionalwireless.com stating that you would like to transfer your IAS license to another computer. If the invoice number for your purchase of IAS is available, please include this in the email to speed up the license verification process. After receiving your email, the license for your copy of IAS will be reset and can then be used on a new computer. Although we will make our best attempt to transfer your license as soon as possible, response times will vary depending on what time of day your request is received.

Does PWS repair wireless gear from other manufacturers?
