{"product_id":"gigahertz-solutions-hf59b-meter","title":"Gigahertz Solutions HF59B High-Frequency EMF Meter","description":"\u003ch2\u003eProfessional RF Measurement with Expandable Frequency Coverage\u003c\/h2\u003e\n\u003cp\u003eThe Gigahertz Solutions HF59B is a professional high-frequency EMF meter designed for detailed measurement of radio-frequency (RF) electromagnetic fields. It combines a highly sensitive, frequency-compensated LogPer antenna with peak, average and peak-hold measurement, audio analysis and quantitative differentiation of pulsed and unpulsed radiation.\u003c\/p\u003e\n\u003cp\u003eThe supplied LogPer antenna covers 700 MHz to 2.7 GHz, with increased tolerance up to 3.3 GHz. The HF59B meter itself is internally open down to 27 MHz and can be expanded with the UBB27_G3 ultra-broadband antenna for measurements across a much wider frequency range.\u003c\/p\u003e\n\u003ch2\u003eWhat Can the HF59B Measure?\u003c\/h2\u003e\n\u003cp\u003eWith the supplied LogPer antenna, the HF59B measures high-frequency sources from 700 MHz upwards, including mobile communication signals such as GSM (2G), UMTS\/CDMA (3G), LTE (4G) and relevant 5G bands, as well as wireless phones, smart meters, Bluetooth and the lower WLAN\/Wi-Fi frequency range.\u003c\/p\u003e\n\u003cp\u003eThe HF59B can also be expanded with the \u003ca href=\"https:\/\/emfprotectionclothing.co.uk\/products\/gigahertz-solutions-ubb27_g3-ultra-broadband-antenna\" title=\"Gigahertz Solutions UBB27_G3 Ultra Broadband Antenna\"\u003eUBB27_G3 ultra-broadband antenna\u003c\/a\u003e. This allows the system to measure from 27 MHz through to more than 3.3 GHz, making the HF59B suitable for applications where a broader frequency range needs to be investigated.\u003c\/p\u003e\n\u003ch2\u003eHigh Sensitivity and Wide Measurement Range\u003c\/h2\u003e\n\u003cp\u003eThe HF59B has a display resolution of 0.01 µW\/m² and a measurement range of 0.01 to 19,990 µW\/m². This provides considerably more resolution at low field strengths than meters with a higher minimum display value, while still allowing substantially higher field strengths to be measured.\u003c\/p\u003e\n\u003cp\u003eAn optional HV10 preamplifier can be used to further increase the sensitivity of the system. For very high field strengths, the optional DG20_G10 attenuator can extend the maximum measurable value by a factor of 100.\u003c\/p\u003e\n\u003ch2\u003eFrequency-Compensated RF Measurement\u003c\/h2\u003e\n\u003cp\u003eThe HF59B uses frequency-compensated measurement so that different parts of its frequency range are not disproportionately weighted. The instrument also displays the combined power density of the RF signals present at the measurement location rather than showing only the strongest individual signal.\u003c\/p\u003e\n\u003cp\u003eMeasurements are displayed directly in power flux density units, including µW\/m² and mW\/m², so no additional conversion is required when taking readings.\u003c\/p\u003e\n\u003ch2\u003eDirectional Measurement with the LogPer Antenna\u003c\/h2\u003e\n\u003cp\u003eThe supplied logarithmic-periodic (LogPer) antenna is both a measuring and directional antenna. This allows you to investigate where RF radiation is coming from as well as measure its field strength.\u003c\/p\u003e\n\u003cp\u003eThe antenna has a frequency response compensated directly on the antenna and is designed for improved accuracy across the measurement range. Its directional characteristics can be useful when locating or investigating individual RF sources, including sources that may not be immediately visible.\u003c\/p\u003e\n\u003ch2\u003ePeak, Average and Peak Hold Measurements\u003c\/h2\u003e\n\u003cp\u003eThe HF59B provides switchable peak and average readings, together with a Peak Hold function. Peak Hold can be useful when investigating signals that vary quickly, as the highest detected value can be retained on the display while the measurement is being carried out.\u003c\/p\u003e\n\u003cp\u003eThe instrument also provides a quantitative differentiation between pulsed and unpulsed radiation using its dedicated measurement circuitry.\u003c\/p\u003e\n\u003ch2\u003eAudio Analysis of RF Sources\u003c\/h2\u003e\n\u003cp\u003eThe HF59B provides an audio signal based on the modulation frequency and field strength of detected radiation. This can help identify and distinguish many pulsed RF sources by their characteristic sound.\u003c\/p\u003e\n\u003cp\u003eSources such as mobile communication signals, DECT and other pulsed transmissions can therefore be investigated not only through the numerical reading but also through the audio output. This can be particularly useful when comparing different RF sources during a measurement.\u003c\/p\u003e\n\u003ch2\u003eCalibrated Signal Outputs for Further Analysis\u003c\/h2\u003e\n\u003cp\u003eFor applications requiring data recording or additional analysis, the HF59B provides both AC and DC signal outputs. The AC output supplies the demodulated signal and is calibrated, while the scalable DC output can be used for applications such as connection to compatible Gigahertz Solutions analysers for longer-term recordings.\u003c\/p\u003e\n\u003ch2\u003eDesigned for Professional RF Measurement\u003c\/h2\u003e\n\u003cp\u003eThe HF59B is suited to users who need more than a basic broadband RF detector. Its combination of high sensitivity, directional measurement, Peak Hold, pulsed and unpulsed signal differentiation, signal outputs and expandable frequency coverage makes it suitable for systematic RF investigations.\u003c\/p\u003e\n\u003cp\u003eThe detailed measurement instructions supplied with the meter also provide guidance on carrying out measurements and interpreting the results in relation to building biology precautionary values.\u003c\/p\u003e\n\u003ch2\u003eExpandable to Ultra-Broadband Measurement\u003c\/h2\u003e\n\u003cp\u003eOne of the main differences between the HF59B and conventional RF meters in this range is its ability to work with additional antennas.\u003c\/p\u003e\n\u003cp\u003eWith the supplied LogPer antenna, measurements start at 700 MHz. When the \u003ca href=\"\/your-ubb27-g3-url\"\u003eUBB27_G3 antenna\u003c\/a\u003e is connected, the HF59B can be used from 27 MHz through to more than 3.3 GHz. This makes it possible to investigate lower-frequency RF sources that cannot be measured with the supplied LogPer antenna.\u003c\/p\u003e\n\u003cp\u003eFor measurements below 700 MHz, the UBB27_G3 is therefore required. The manufacturer's documentation also notes that the isotropic UBB antenna can be advantageous for long-term data logging and broad surveys, while the directional LogPer antenna is particularly useful when locating individual RF sources.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x: auto;
