The 5 Best Portable Frequency Counters

Portable Frequency Counter Reviews

Portable frequency meters are designed to count the continuous wave signals transmitted from two-way radios. They are frequently employed by maintenance professionals as well as hobbyists to test and detect frequencies and signal strengths.

The 5 oz., Signstek 50 MHz, 2.4 GHz handheld frequency meter is our top pick- it includes a screw-in antenna, an RF level display, quality back-light and rechargeable battery. Its users commend its ability to automatically save readings in memory storage- endorsing its capacity to process two-way radios, car remotes, and general radio-frequency snooping.

It can pick up frequencies ranging from 50 MHz to 2,400,000,000 MHz. Users do say that the supplied antenna has a narrow band that primarily will detect the strongest signal that is in range- sometimes you will need to use a custom front-end filter to specifically detect signals you are going after.

All that said, this is a solid and inexpensive handheld wave signal frequency counter that's received quality buyer feedback.

Let's take a look at five of the best-selling radio frequency handheld meters on the market today and see how they compare.

Some people who have purchased this portable frequency counter have noted that even though it is accurate for various frequencies and CTCSS codes, it is pretty unreliable for any DCS codes. Other users have noted that you need to be really close to measure any radio that has low power or it can’t pick up the frequency to measure it.

Pros

  • Inexpensive
  • Accurate for frequency counting and CTCSS codes
  • Lightweight
  • Compact
  • One button control system
  • Easy to use and read

Cons

Portable frequency counter buying guide

Individuals that purchased these highly portable frequency meters were generally interested in assessing the parameters of walkie-talkies with continuous carrier signals.

Some of the common features that users prioritize when assessing the different wave signal frequency counters on the market are automatic off switches, automatic LCD backlights, integrated rechargeable batteries, removable antennas, low battery indicators and memory storage functionality.

User feedback

Some valuable user insight from community members include the recommendation that you not skimp when purchasing a miniature radiofrequency meter. That said, there are some really affordable options on the market- and they are a great place to start before you invest in something more sophisticated.

The way they work, is that you turn on the frequency counter by holding the on button for a second, switch on your radio, make sure that the two antennas are touching, then you'll hold down the transmission button for a few moments until you have captured the frequency.

Pause for a few seconds at this point before holding down the transmission button again. If you are looking to capture CTCSS codes you do not need to hold as long as you do for DCS codes, which in the case of the NSKI frequency meter requires up to 20 seconds of button-holding to capture. Some users who purchased less expensive options complain about the flimsy build quality and the antenna that oftentimes arrived broken in shipping.

Another common complaint is that the manufacturers sometimes oversimplify the user interface- consolidating all functionality into one button, which can make operation more rather than less confusing.

This manifests when users were attempting to select a frequency range because the time out for the stop was so quick that it would take several attempts before you get what you wanted. In all, it would seem to make sense to invest in a quality model to start with rather than opt for a less expensive option that might arrive broken or lack the functionality and dependability of a higher-priced radiofrequency counter.
