What is a Log Periodic Antenna?

How do LP Antennas Work?

Log Periodic Dipole Array (LPDA) antennas are directional, active broadband antennas that are the ideal solution for interference tracking, site surveying, and most general RF and EMC analysis applications, due to their unique dipole elements positioned along the antenna axis in a triangular shape. With many varieties and names (LP Antenna, LPDA, LP Array Antennas, and Log Periodic Aerial) and minor functionality and design variations amongst each type, these antennas are designed with optimization in specific frequency ranges, and are capable of functioning within the high frequency – extremely high frequency ranges. Aaronia USA offers LP antennas starting as low as 380 MHz, and as high as 35 GHz to cover all potential RFI detection applications. [Read more…]

What is a Faraday Cage? How do you build a Faraday Cage?

What is a Faraday Cage?

By definition, a faraday cage is an enclosure created with conductive materials (most commonly metal screens) that blocks both static and non-static external electric fields. Invention and naming is credited to Michael Faraday, who constructed a room lined with metal foil in 1836 and used an electrostatic generator to create high-voltage discharges on the outside of the room. He then used an electroscope to prove that there was no resulting electric charge on the inside walls. [Read more…]

AaroniaUSA Antennas are Unstoppable – Even in Extreme Snow

An FAA station in Alaska, northwest of Fairbanks and just south of the Arctic Circle, uses an AaroniaUSA HyperLOG 6080 Log Periodic Antenna for RFI detection in extreme snow and ice. We love our customers, and we love even more when they send great pictures of their unique AaroniaUSA product applications.

While we do sell tripod stands, some customers prefer to play in the snow instead, using shovels and tape to rig a temporary antenna mount. An icy example of engineer ingenuity.

Cold as it may be, there is no denying the beauty of the remote Alaskan landscape.

AaroniaUSA Antenna, RF Analyzer, and EMC Shielding lines all include products designed to withstand extreme environments, including the icy blasts of the arctic, desert heat, and tropical rains. For more information on selecting the appropriate RF analyzer for your extreme temperature or harsh environment application, contact an Application Specialist at sales at aaroniausa.com or call 214-935-9800.

The Full Spectrum of RF Congestion

Last week, the FCC unanimously approved a proposal opening up frequency bands above 28 GHz (millimeter waves), including licensed bands from 27.5 – 28.35 GHz, 37 – 38.6 GHz, and 38.6 – 40 GHz, and unlicensed band between 64 and 71 GHz. This proposal was brought forth as a result of successful testing for 5G networks, using small cells to send data to mobile devices, with significantly improved response times and download speeds than 4G. With anticipated public access in 2020, the enhanced speed and performance of 5G networks will bring better streaming quality, virtual reality, and seemingly “instant” downloads into the hands of the general wireless consumer.

What are Smart Meters? How are they dangerous?

With the use of personal, consumer electronic RF transmitters on the rise, AaroniaUSA’s team of application specialists receives more and more calls each day from customers wondering how they can protect themselves from these rampant EMI and RF transmissions. One of the most common complaints, however, is the Smart Meter. Smart Meters are RF transmitters that utility companies use to digitally transmit meter readings directly to their computers without a technician manually reading utility meters on your property. They run 24/7, and although they do not transmit 24 hours a day, most do transmit data at least once daily. Smart Meters have grown in popularity over the past several years, and are now used by utility companies in several states.

As popular as they may be amongst utility companies, smart meters are controversial amongst consumers, and are often considered dangerous or hazardous to health and safety by people who are sensitive to RF and EMI transmissions. Negative health impacts reported include high pitched ringing sounds, headaches, insomnia, and fatigue. Read more about RF Exposure’s negative impact from OSHA.
