I did get mine from Amazon, viz: https://www.amazon.co.uk/gp/product/B08HVJ8ZSF/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 which is fine. However, I'm told that, to be safe, Mirfield Electronics would be wiser. **Q: Exactly how can I use this to find out the frequency of something?** A: if you highlight the markers and scan up and down the peak freq will be highlighted **Q: Can this be used to connect a directional antenna (used for a sim card huawei router) to fine tune the antenna direction for maximum signal reception?** A: Hi Paul, If the router uses the 800 or 900mhz 4G bands then possibly yes, but if the router uses the 1.8Ghz band then no as the maximum frequently of the Mini SA is 930Mhz. I hope this helps. Kind regards, D. **Q: will this help me to work out if someone is trying to jam my wifi? thanks** A: Very doubtful: I don't think that the SA gets up to wifi. frequencies (2.4 and 4 GHz). Most conflicts between wifi users relate to a very crammed bandwidth so other households are likely, quite inadvertently, to conflict with one another's traffic. ## Frequently Bought Together - Seesii Portable TinySA Spectrum Analyzer, Upgraded V0.3.1 Handheld Tiny Frequency Analyzer 100kHz to 960MHz MF/HF/VHF UHF Input,Signal Generator with 2.8 inch Touch Screen with ESD Protect Function - YILIANDUO 4 Pieces SMA to BNC Adapter Kit 50 Ohm SMA BNC Connector Male Female RF Coax Adapter set for Baofeng Antenna, SDR, Handheld Radios, Scanner, Walkie Talkie Adapters - YILIANDUO 10 Type Set SMA Adapter Kits SMA Male to N/F/BNC/UHF/MCX/SMB/TV/TNC Female Straight Nickel Gold Plated Test Converter for WiFi Antenna SMA Software Defined Radios Devices --- ## 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.co/products/230592854-portable-tinysa-spectrum-analyzer-upgraded-v0-3-1-handheld-tiny](https://www.desertcart.co/products/230592854-portable-tinysa-spectrum-analyzer-upgraded-v0-3-1-handheld-tiny) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-08*
