SOTABeam Low Pass Filter Kit

/

SOTABEAMS has introduced a new low pass filter kit. Low pass filters are an essential part of any transmitter and also have applications in receivers.

The kit allows one of two filters to be selected and also incorporates a "bypass" mode. SOTABeams have designed the low pass filter kit to complement the WSPRlite Classic HF antenna testing system. To give users the most flexibility, the filter components are available separately to allow filters from 160 m through to 10 m to be constructed.

Antenna Manufacture Ceases Production

/

Polar Electronic Industries of Australia, who have designed and manufactured antennas for 41 years have ceased trading, ending the supply of antenna to amatauers in 51 countries. The company specialised in producing none standard antennas outside the usual commercial frequency range. 

Among the Polar products covering 2 MHz to 2.9 GHz were communications antennas, multicouplers, duplexers and accessories. Retirement of its two engineers and owners is given for the closure. Based at Moorabbin in Melbourne’s south, it had extensive engineering and test facilities, including computer-aided radiation measuring equipment. Through research and development it remained an industry leader. 

The directors Ben Czerniewicz and Neville Sleep, were always ready to provide special product for mountain top repeaters, using the heavy duty methods of standard commercial frequency antennas. WIA Repeater & Beacon Coordinator, Peter Mill VK3APO said he had found nothing matches the ruggedness and longevity of Polar antennas, and loss of that source with its excellent customer service has come as a surprise and shock. The decision affects lots of repeater owners throughout Australia and beyond.
