Regular price $190.00 Sale

Amplifies Weaker Signals by 10x and Aids with Source Identification - Compatible with: Standard Log-Per antenna or the UBB27 antenna of the HFE35C, HF58B, HF58B-r, HF59B, HFE59B RF Meters.

Increase the sensitivity of your RF Meter with the HV10_27G3 Preamplifier (Amplification factor of 15dB (10x))

If your RF Meter measurement range is set to its finest range and you are suspicious of the presence of a weaker signal, this preamplifier allows the RF Analyzer to accurately display the weaker signal strength measurement.  

Adding the HV10_27G3 to your RF measurement equipment will:

  • Pinpoint small field strength signals which are below the lower field strength limit of the RF Meter
  • Extend the sensitivity of your RF Meter by 10 times in the frequency range of 27 MHz - 3 GHz
  • Allow for field strength measurement of RF signals which are off the low end scale of the RF Meter  


How it Works:

  • Attach the HV10_27G3 Preamplifier to a compatible RF Analyzer (RF Analyser)
  • Attach the LogPer directional antenna or the UBB27 multi-directional antenna to the HV10_27G3
  • Power on the RF Analyzer and configure appropriately
  • Hold the RF Analyzer with an outstretched arm
  • The analyzer will display the intensity of RF radiation on its LCD display
  • Simply divide the displayed value by 10 to obtain the actual value
  • If using the HF59B or the HFE59B, power level adapter switches can be configured to automatically display the actual value


Compatible with: HFE35C, HF58B, HF58B-r, HF59B, HFE59B
