Highly priced
Not bad but very expensive for what it is. Bought it just because I trust the brand. Nasty price though.

Parfait !
Accessoire qui fonctionne parfaitement bien. Discret et esthétique, il trouve sa place très facilement dans une installation SDR. Je recommande à 100%.

安全性の確保
ＳＤＲ用の保護とスペアナの保護に使っています。 もう少し長さが短いと使い勝手が良いのですが、長過ぎます。

Matches Spec
Remember, these are for SHORT TERM use. You do not use them at the top of it's rated DC power while doing TX or RX for long periods (multiple hours), They will get hot, and that will impact your signal.

Passt.
Da für dieses Produkt bisher keine Kommentare und nur eine extrem dürftige Beschreibung vorhanden waren, war ich skeptisch. Habe trotzdem bestellt und auf den ersten Blick macht das Teil einen guten Eindruck. Verarbeitung ist gut, DC wird geblockt (noch nicht getestet, ob wirklich bis 50V, wie angegeben) und die Dämpfung hält sich arg in Grenzen, wie es sein soll. Anbei ein Plot, den ich mir in der Produktbeschreibung gewünscht hätte: S21 Gain Hier gemessen mit einem nanoVNA, kalibriert auf die verwendeten Messleitungen (Device-Kalibrierung & Nanovna-saver-Kalibrierung). Aufgrund des preiswerten Messequipments natürlich nicht unendlich aussagekräftig, speziell zu höheren Frequenzen hin - aber besser als nix.
