I mainly use it for verifying ENG wireless microphones during press check-ins. Don't typically get a reading until under 20" away from the TX source. **Q: Does it come with both the vhf and uhf antena?** A: This unit comes with (1)one 5" universal antenna that seems to cover the vhf/uhf frequencies very well, it even works well down to 72 MHz (model aircraft radio) not so much at 2.4gHz range. **Q: Could I use this to find out Hz vibration plate vibrating at?** A: This item only picks up RF frequencies. Vibration plate is an audio wave form I believe? You would need a sound wave sensor to see the frequency such as a Accelerometer. This is a sensor that measures the dynamic acceleration analyzer of a physical device as a voltage & frequency. **Q: Will this count cell phone frequencies (i.e. 4G)?** A: No it does not ## Frequently Bought Together - Surecom SF401 Plus 27Mhz-3000Mhz Radio Portable Frequency Counter Meter with CTCCSS DCS Decoder - XRDS-RF 50W PL259 UHF Male Plug RF Dummy Load, 50 Ohm - Surecom Gam3Gear SW-102S SO239 Connector Digital VHF UHF 125-525Mhz Power & SWR Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/69765552-surecom-sf401-plus-27mhz-3000mhz-radio-portable-frequency-counter-meter](https://www.desertcart.jp/products/69765552-surecom-sf401-plus-27mhz-3000mhz-radio-portable-frequency-counter-meter) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-23*
