This new version of PA0NHC MiniWhip Antenna has these features.New version, using modern BF998 and BCX54 semi conductors.Real class A circuitry, clean reception without IMD.One coax connection.Broadband R/C coupling to the receiver, no transformer For best signal-to-noise ratio:install the Miniwhip onto a well grounded mast.connect "GND" of the Miniwhip PCB to that mast.place HI-Ui ferrite cores (Ui bwtween 5000 and 10.000) on the beginning and end of all cables to block cable noise currents. Specifications: Frequency range: 10 KHz - 30 MHz Power: 12 - 15 volts at 150 mA Second order output intercept point: Greater than + 70 dBm Third order output intercept point: Greater than + 30 dBm Maximum output power: in excess of - 15 dBm PCB Size: Length (mm): As the picture show Connector: BNC Feed line: 50 - 100 ohm coaxial cable up to 100 meter long T o note please: Each antenna performs as good as its installation permits it to. Any active antenna is not working good inside the house! It should be mounted OUTSIDE and as high as possible. Place this MiniWhip antenna PCB inside suitable enclosure of your choise and mount outside the house. Probably for the enclosure you can use a piece of the PVC tube which available in varios diameters in a local store. Do not use metal enclosure! It wont work there! For max. sensitivity: this antenna should be positioned as high and free from meta Package include: 1Set Board Note:   The color might be a little different from the actual product due to color display of different monitors.  Please allow 1-3 cm error.

Vous souhaitez émettre ou juste recevoir sur plusieurs bandes HF mais vous manquez de place... Choisissez la OTURA 3 ! C'est une antenne multibande HF constituée d'un fouet vertical de 8,25 m couplé à un unun de rapport 1:4, elle fonctionne sans trappe (qui limitent la bande passante) ni radian. Facilement et rapidement installée, la OTURA 3 vous comblera par ses performances et sa robustesse ! Le diamètre des tubes (35 mm à sa base) et la hauteur de l’antenne permettent un fonctionnement depuis la bande des 3,5 MHz. L’utilisation d’un coupleur automatique ou manuel, avec une large plage d'impédance, est préférable pour profiter pleinement de toutes les bandes HF. Cependant, le ROS est inférieur à 2:1 sur de nombreuses bandes et même à 1,5:1 sur plusieurs ! La OTURA 3 peut être fixée sur un mat ayant un diamètre jusque 50 mm, sa puissance admissible est de 400 watts (voire plus selon le type d'alimentation). L'attaque peut se faire "normalement" (basse impédance) avec un câble coaxial mais également en "haute impédance" (sans le unun 1:4) par une ligne bifilaire, dans ce cas, la puissance admissible dépend de la ligne d'alimentation. Une longueur de câble coaxial de bonne qualité d'un minimum de 35 m est recommandée. Fiche technique Bande de fréquences - Bands 3-30 MHz Diamètre des éléments - Elements diameter 35/31 à 12/10 mm Hauteur - Height 8,25 m Puissance admissible - Maximum power 400 W PEP Impédance - Impedance 50 ohms Connecteur - Connector SO-239 (PL) Poids - Weight 4,5 kg
