Gigahertz Solutions HF59B
Professional RF analyser with switchable peak and true-RMS detection, 700 MHz – 2.7 GHz with the supplied log-periodic antenna (−3 dB at 3.3 GHz) or 27 MHz – 3.3 GHz with the isotropic UBB27 antenna, reading 0.001 µW/m² to 1,999 mW/m² depending on preamplifier and attenuator.

- With DG20 attenuator
- up to 1,999 mW/m²
- With HV10 preamplifier
- down to 0.001 µW/m²
Calibration
Manufacturer factory calibration; Gigahertz Solutions offers recalibration and a two-year warranty on the meter, antenna and accessories.
Suited to
- Building-biology surveys at the very low levels precautionary targets use: with the preamplifier the floor is 0.001 µW/m²
- Deciding between peak and true-RMS on the same instrument, which is what makes a reading comparable with a time-averaged limit
- Locating a source by direction with the log-periodic antenna, then quantifying total exposure with the isotropic antenna
What it cannot do
- No low-frequency capability — Gigahertz Solutions sells the separate ME and NFA lines for that
- The base configuration starts at 700 MHz, so 5G in the 600 MHz band, TETRA and FM need the UBB27 antenna
- Nothing usable above 3.3 GHz: 5 GHz and 6 GHz Wi-Fi and mmWave 5G are out of range, and the maker's HFW35C and HFW59D cover those instead
- A directional antenna reading is not total exposure: pointing it at the strongest source deliberately excludes the rest
- Below the far-field distance (roughly 27 cm at 2.7 GHz, 2.7 m at 270 MHz per the manual) a power-density figure is not meaningful
- No on-device logging; the DC output has to feed an external recorder
What these figures are
Every number on this page is the manufacturer's own declared specification, reproduced so that models can be compared field by field. Nothing here is an independent test of the instrument, a calibration certificate, or a statement that a reading taken with it can be compared with a regulatory limit — that depends on the detector, the averaging and, where it matters legally, an accredited calibration.
Where to buy
EMR Shielding Solutions is a related company of WebKMS, which publishes EMFBase, and sells this product. The link is a stockist listing only: every figure on this page comes from the manufacturer's own documentation, and no specification, limitation or citation depends on it.

Beyond roughly a wavelength from an antenna the field behaves as a propagating wave and inverse-square estimates apply; closer than that they do not.
