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.

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?
Although PWS sells gear from all major wireless audio manufacturers, PWS only services equipment manufactured by PWS.

Do I need a RA# for PWS manufactured equipment repair?

Antenna Systems

Antenna Systems can make or break an wireless system installation. The engineers at Professional Wireless Systems can assist you in determining the best types of antennas and cable for your needs. Below is a list of common types of antennas. Each antenna has it’s own advantages and disadvantages. It’s not really possible to say that any one antenna is best or worst. That determination can only be made on a case by case basis for each installation.


Other Accessories such as multicouplers, line amplifiers, passive combiner / splitters and filters are also part of the antenna system. Let PWS provide you with “Custom Solutions” for your installation. Entire installation packages are available on a custom designed basis.
