Very happy with this purchase. ### ⭐⭐⭐⭐⭐ In Verbindung mit... *by P***. on 19 June 2023* …den auch bei Amazon angebotenen „TINY SA Ultra“ oder dem TINY SA“ ist dieses hier zu besprechende >>BECEN 10 W SMA RF-Dämpfungsglied, DC bis 3 GHz, 40 dB.<< unabdingbar, möchte man seinen TINY-SA nicht durch zu große Energie zerstören. Die max. Leistung, die in das Gerät eingebracht und zur Messung verwendet werden darf liegt bei 6dB (oder 3,98 mW {milli-Watt!!!}) betragen, jede größere Leistung ZERSTÖRT das TINY-SA ULTA! Also Vorsicht!!! Auch mit der mitgelieferten Teleskop-Aufschraub-Antenne des TINY-SA Ultra kann dieser Max.-Wert schnell überschritten werden, deswegen unbedingt dieses Dämpfungsglied an den Eingang des TINY-SA anschrauben und daran am, anderen Ende das Prüfobjekt. Sollten Sie z.B. ein Handfunkgerät auf Oberwellendämpfung überprüfen wollen und den Antennenausgang an dieses Dämpfungsglied anschließen wollen, darf die Sendeleistung keinesfalls die>> 5 WATT << Überschreiten, um den TINY-SA auch mit aufgesetztem Dämpfungsglied nicht zu überfahren. Somit erfüllt dieses Dämpfungsglied die Voraussetzungen, mit einem TINY-SA (ULTRA) überhaupt Funkgeräte bei max. 5 Watt Leistung aus zu messen. Somit MUSS ich dieses Dämpfungsglied hier einfach als unbedingt notwendig für Messungen mit dem TINY-SA (ULTRA) empfehlen. Ich habe damit erfolgreich einige Handfunkgeräte für den Amateurfunkbereich erfolgreich und ohne Zerstörung des Messgerätes messen können! Also schreibe und empfehle hier aus Praxiserfahrung. Ich bedanke mich herzlich bei Ihnen für Ihr Interesse an dieser Rezension sowie diesem, von mir empfohlenen Produkt und hoffe ein wenig bei der Produkt-Einschätzung hilfreich gewesen zu sein. ## Frequently Bought Together - BECEN 10W SMA Attenuator,40db,DC to 3GHz,50 Ohm - DHT Electronics Handheld Antenna Cable SMA male to UHF SO-239 Female Connectors 6'' Pack of 2 - AURSINC Upgraded 4.0 Inch TinySA Ultra Spectrum Analyzer, HW V0.4.5.1 100kHz-5.3GHz Handheld Frequency Analyzer with 32Gb Card, 2-in-1 Signal Generator 100kHz to 800MHz MF/HF/VHF UHF Input --- ## 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.za/products/439773416-becen-10w-sma-attenuator-40db-dc-to-3ghz-50-ohm](https://www.desertcart.co.za/products/439773416-becen-10w-sma-attenuator-40db-dc-to-3ghz-50-ohm) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-23*
