Specification: 100% brand new and high quality. Applications: HF antenna balun, SDR/amplifier ESD protection Antenna Input: Spring-type terminal Block RF Output: Female SMA Dimensions: 39.2mm x 13.0mm Package includes: 1pc Features: Meet 'Balun One Nine', a small, cost-effective balun. An excellent way to attach a long wire or dipole antenna to the Ham It Up, or any other HF-capable radio, this 9:1 balun has an SMA output port and high-quality spring-type terminal block input for your coax. Balun One Nine includes an AntennaGuard varistor on the input, protecting your SDR setup from spurious ESD. The ESD protection is excellent--it passes IEC61000-4-2, an 8kV contact discharge test, with a response time of just 300ps. At 39.2mm x 13.0mm in total size (including connectors!) this balun was designed to be light in weight and light on your wallet. Very low insertion loss of -1.3dB (typical), with a maximum input power of +28dBm. Designed for HF applications, but specifications are accurate to frequencies up to 90MHz+.   Specification: 100% brand new and high quality.

Miniwhip Active Antenna HF LF VlF Mini Whip Shortwave SDR RX Portable Recei M ZH Description: MINIWHIP VLF LF HF ACTIVE ANTENNA.This is known PA0NHC newest design of MiniWhip Antenna. I have redesigned and built it on SMD components but the circuit diagram itself stayed the same as it had been described on his web page in open source. This sale includes the MiniWhip and Power Splitter assembled and tested boards. They go with its circuit diagrams and part list specification. No cables or connectors are included. 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!

Radio Beacon NDB transmitter HF. It has a DDS generator with a step resolution of 1 Hz from 1 to 55 MHz. The final stage (30 W max power) is set to deliver 5 W. It may be set from 3.5 to 15 MHz (may be modified for 30 Mhz operation. The power supply (120 W) works from 100 to 280 Vac and it’s built in. No fans, no noise. The RF stage an oversized heatsink for continuous operation. The radio beacon has a directional beacon to indicate the forward and reflected power. The ID and the Morse code text may be easily reprogrammed, as well as the keying speed and the pause duration just connecting a PC via USB port using a simple code (provided). Very good stability in power and amplitude. For any further information you are welcome to ask !

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

NanoVNA 50KHz-900MHz HF VHF UV Vector Network Antenna Analyze+LCD ZH Description:    Manual download   Simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50535-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 60dB of dynamics, and the 600M-900M band is better than 50dB of dynamics.   This is a DIY product that provides perfect vector network measurement capabilities in the size of a credit card. It includes a 2.8-inch touch screen and 500mAh battery, which can be used offline for 2 hours. For longer measurement, please connect external power supply or contact me to make a larger battery version. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring.           Basic performance:   ● PCB: 54mm x 85.5mm x 11mm (without connectors, switches) ● Measurement frequency: 50KHz ~ 300MHz (50KHz -900MHz, enable extended firmware) ● RF output: -13dbm (maximum -9dbm) ● Measurement range: 70dB (50kHz-300MHz), 60dB (300M-600MHz), 50dB (600M-900MHz) enable extended firmware); ● Port SWR: ● Display: 2.8 inch TFT (320 x240) ● USB interface: USB type-C communication mode: CDC (serial) ● Power: USB 5V 120mA, built-in 300mAh or 500mAh battery, maximum charging current 0.8A ● Number of scanning points: 101 (fixed) ● Display Tracking: 4   ●  Marking: 4   ● Setting Save: 5   ● Measuring S parameters, voltage standing wave ratio, phase, delay, Smith chart...     Package list:   1X NanoVNA host (with 500mAh battery)   1X USB Type-C data cable

Amplifier HF 1200 W 8 X MRF151 With Heatsink for HAM Radio Bands. The pallet has a massive copper plate of 5 mm. It is fixed to the aluminum heatsink of 3 kg. Super robust construction. The pallet requires a 50 Vdc 38 A power supply. The enable input accepts from 5 to 24 Vdc, 300 mA. The pallet has 8 trimmer for biasing adjust. Each mosfet has its current measurement output. On the PCB the current values table is clearly marched on the components side. The bias has been already set, so the amplifier is ready for use. The amplifier is tested and requires a drive power of 20 W max. Just the copper plate and the heatsink has a very good value. For shipping costs to the countries non specified in the bid, please ask for a quotation. The item is quite heavy.

Specification: 100% brand new and high quality. Applications: HF antenna balun, SDR/amplifier ESD protection Antenna Input: Spring-type terminal Block RF Output: Female SMA Dimensions: 39.2mm x 13.0mm Package includes: 1pc Features: Meet 'Balun One Nine', a small, cost-effective balun. An excellent way to attach a long wire or dipole antenna to the Ham It Up, or any other HF-capable radio, this 9:1 balun has an SMA output port and high-quality spring-type terminal block input for your coax. Balun One Nine includes an AntennaGuard varistor on the input, protecting your SDR setup from spurious ESD. The ESD protection is excellent--it passes IEC61000-4-2, an 8kV contact discharge test, with a response time of just 300ps. At 39.2mm x 13.0mm in total size (including connectors!) this balun was designed to be light in weight and light on your wallet. Very low insertion loss of -1.3dB (typical), with a maximum input power of +28dBm. Designed for HF applications, but specifications are accurate to frequencies up to 90MHz+.
