Vraiment surprit
Ampli très éfficace j'adore, j'ai ajouté un fil usb pour son alimentation externe Bias-T et sa fonctionne a merveille, merci pour votre service .

Over my expectations
This small module exceeded my expectations! I do believe that this was not my last purchase of this item!! I think every FM radio should have one LNA like this at the input stage!
rating 5
Efficace
LNA très efficace, mon signal est amplifié de 18dBm sur les 400MHz, et sans bruit supplémentaire.
Ceci dit, il vous faut investir dans une très bonne antenne et un très bon coax, ce LNA n\'est pas magique sans un bon matos

Un petit deuxième pour la route !

J'ai été obligé de changer le précédent qui n'a tenu que quelques semaines, bonnes raisons inconnues, et que Passion-Radio a eu la gentillesse de me renvoyer. C'e très bon, préamplis, totalement avare en QRM, amplifie des signaux extrêmement faible en UHF, VHF pour le retranscrire sur mon récepteur avec fidélité

Très bien réalisé, très bonne qualité.

Très faible bruit.

Très performant !

Un très bon préampli pour UHF/VHF mais pas que ..... ; très puissant il arrive à couvrir de façon surprenante le 40 mètres . Je me surprend très souvent également a être obligé de supprimé tout les mode de préamplification en réception de mon récepteur tellement le gain et concidérablement élever.

Parfaitement adapter

Un petit préampli UHF/VHF très éfficace , et surtout il n'amplifie pas les QRM. Ont peut remarquer que la qualité générale de cette minuscule carte cms et parfaite avec une qualité des soudure et de conception qui fait vraiment plaisir à voir. Pour sont alimentation j'ai préféré lui fournir une tension de 9V max avec un adaptateur USB débrochable connecter sur chargeur de type iPhone ( comme le préampli de la MLA-30+ ). N'oubliez pas de rajouter avec celle ci le petit boitier aluminium qui sert notamment de conducteur thermique pour le refroidissement des petit cms.....

Questions

Question

Je voudrais savoir comment faire pour l'alimentation externe. Que faut-il prévoir, je voudrais amplifier le signal de mon antenne vers la radio. Merci d'avance pour votre aide précieuse.

Answer

Sur ce matériel l'alimentation peut se faire de 8 à 14V, en soudant le fil positif (+) sur la carte PCB sur VCC, et souder le fil négatif (-) sur IN.

Ou bien, il est possible d'alimenter ce LNA via le câble coaxial et un BIAS-T.

Par contre on ne peut utiliser qu'un seul principe d'alimentation à la fois.
