Save your money. **Q: So239 connectors are shown. Please verify?** A: This video is the size of the connector. **Q: How do you use the Booster Board please?** A: I believe the intent of the booster board is to power the unit using a USB device. This unit requires very little power to operate, so instead of powering it via a 12V supply (battery), one option is to bring a USB battery bank or similar power device and, using this cable/board, power the unit. That's my guess. **Q: What is the swr matching range and the impedance matching range?** A: For my use and what you want to connect to this device impedance wise, 50 ohms from the transmitter and the antenna is optimal. But the purpose of this unit is not only to display the SWR but to improve a mismatch of impedance between the transmitter and the antenna. On frequencies where I have a mismatch between my transmitter and antenna, this device does a good job matching the impedance where my SWR is usually below 2.5. ## Frequently Bought Together - Malahit ATU-100 EXT Antenna Tuner 1.8-50MHz atu100 by N7DDC 7x7 0.96 Inch OLED 3.2 Firmware Programmed with Housing Assembled Machine with USB Cable（No Battery） - Superbat UHF Male PL-259 to UHF Male PL-259 Low Loss Digital Coax UHF Jumper Cable (2ft RG58) for HAM & CB Radio,Antenna Analyzer,Dummy Load,SWR Meter - Superbat PL-259 Jumper Cable UHF (Pl259) Male to Male Low Loss Digital RG58 Coax Cable (12 Inch RG58) for HAM & CB Radio,Antenna Analyzer,Dummy Load,SWR Meter 2-Pack --- ## 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.tn/products/359745843-malahit-atu-100-ext-antenna-tuner-1-8-50mhz-atu100](https://www.desertcart.tn/products/359745843-malahit-atu-100-ext-antenna-tuner-1-8-50mhz-atu100) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-05*
