HFEW35C Ultra-wideband RF Analyzer Set 
Comprehensive and future-proof for EHS - "5G ready"
HFE35C + HFW35C cover frequencies from 27 MHz to 6,000 MHz.

Features

The extra-wide frequency range, intelligently divided into two separate devices, and the quasi-isotropic reception characteristic provide a comprehensive picture of the exposure situation. It helps electrosensitives (EHS) assess their environment to find "their place." Suitable for determining meaningful remediation measures and monitoring their effectiveness.

Based on the proven HF analyzers HFE35C AND HFW35C:

  • Covers all mobile services (GSM, UMTS, LTE, 2G, 3G, 4G, 5G (all "Sub-6 GHz" bands)), DECT, both WLAN/WiFi bands, WiMAX as well as radio, TV, TETRA/BOS, and multiple radar frequencies. And everything in between.
  • Measuring the upper frequency band with a separate device, the HFW35C, ensures that the two WLAN/WiFi bands, considered particularly critical by building biology experts, are not overlooked, as they are often "overshadowed" by the usually stronger lower frequencies.
  • HFW35C: Includes a specially tuned, patented LogPer antenna with very good directional characteristics.
  • HFW35C also includes the professional function of quantitatively differentiating pulsed <> unpulsed radiation according to building biology recommendations for the frequency range from 2.7 GHz to 6 GHz.
  • HFE35C is supplied with two antennas.
  • The horizontally isotropic ultra-wideband antenna UBB27_G3 extends down to 27 MHz (so-called "omni" characteristics) and covers, through its small resonator, even tiny but often larger local maxima that are not visible with the larger LogPer antenna but are of great building biology relevance.
  • The specially compensated LogPer antenna for the range above 800 MHz is used for the secure localization of radiation sources.
  • Supplied in a compact plastic case K5 with foam insert for secure transport of the measuring instrument with the two antennas.

Benefits

Of course, the HFE35C and HFW35C fulfill all additional advantages of the series:

  • It is fully frequency-compensated, meaning no frequency range is overvalued, undervalued, or even ignored.
  • Our measurement technology fundamentally shows the SUM OF ALL radiation present at the measurement location, not just the strongest frequency, which is common in the cheap, supposedly broadband detectors that have come on the market in recent years.
  • The two aforementioned features are crucial for an informative measurement and technically challenging to implement. This is also the reason our devices are unique in their respective price ranges.
  • Measurement values are reliably and directly displayed in units corresponding to building biology precautionary values. Without any calculations required.
  • All our HF analyzers are also equipped with a fully-fledged LogPer directional/measurement antenna. This sets them apart technologically from compact pocket devices without an external antenna. This allows users to detect and measure even hidden sources of high-frequency electromagnetic radiation (HF). Measurements can be performed both indoors and outdoors (protect the instrument from moisture!).
  • With audio analysis, even technical laypeople without electronic knowledge can distinguish most radiation sources such as mobile telephony, WLAN/WiFi, DECT, radar, etc. Simply by listening and comparing with the provided sound samples.
  • A detailed step-by-step measurement guide is included with all our devices. This naturally also includes building biology guideline recommendations – enabling even individuals without technical expertise to reliably assess the exposure situation.
  • Not to be forgotten: All our electrosmog measuring devices are also extensively patented, proven practical thousands of times worldwide, and groundbreaking in their respective price ranges.
