Comes with a very easy to use and mount dipole, extremely simple to set up even for beginners. When set up correctly has very good signal receiving quality. The USB itself is tiny but the dipole can get extended to whatever length needed (well, until you can't extend it anymore!). Build quality is really good and it functions amazingly; I haven't even used this with a standard SDR program yet, but my own Python script I have been writing for direction finding and signal analysis - works perfectly (as long as you have the correct drivers&libraries installed!).This is definitely something beginners can use as well as people more experienced too - highly recomend! ### ⭐⭐⭐⭐⭐ βœ…οΈ device as described. *by on Reviewed in the United Kingdom 1 June 2026* Great device and easy install and setup in Linux on Raspberry Pi 5, drivers avaliable github respiratory. Got quite good coverage with supplied antenna. Tracking over 100 vessels on first try. The chip runs at 50Β°C so use extra USB2 or 3, 0.5m cable between the chip and the pc. ### ⭐⭐⭐⭐⭐ Decent little SDR dongle *by on Reviewed in the United Kingdom 23 July 2024* If you’re buying this then you probably know what you want but in a nutshell this single works well with almost all operating systems and SDR applications. I was impressed with the included accessories. Easy to set up. Good value for money. Stays fairly cool during operation with its metal casing. Good reception, better than my handheld scanner in the same location. ## Frequently Bought Together - RTL-SDR Blog V4 R828D RTL2832U 1PPM TCXO HF Bias Tee SMA Software Defined Radio with Dipole Antenna Kit - The Hobbyist's Guide to the RTL-SDR: Really Cheap Software Defined Radio - RTL-SDR Blog V4 R828D RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/584115002-v4-r828d-rtl2832u-1ppm-tcxo-hf-bias-tee-sma-software](https://www.desertcart.co.za/products/584115002-v4-r828d-rtl2832u-1ppm-tcxo-hf-bias-tee-sma-software) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-03*
