This project assembles a 49:1 ferrite-core (“FT”) type #43 transformer that matches 50 ohm input to 2500 ohm end fed antenna. It is optimized for 3.5/7/10/14 MHz but will work reasonably well on all
An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground.
For it's simplicity and small dimensions is very popular for portable or SOTA activities, and also as a static-mobile antenna. This Mini 49:1 UnUn can be used also as the base point of a vertical dipole antenna with its half wave length. MULTIBAND ANTENNA.
22 lut 2021 · The following is a list of materials required to make a 49:1 unun impedance transformer for an end-fed half wave antenna. You will also need a half-wavelength length of wire (14 or 12 gauge typically) in order to construct an antenna radiator for whichever ham band you choose.
20 lip 2024 · UnUn 49:1 – 500W do End Fed + Balun 1:1 2kW w zestawie taniej W skład zestawu wchodzi: Balun UnUn 49:1 na pasma KF transformator antenowy o mocy max. 500W SSB dedykowany do anten o impedancji 2540 Ohm np.
For those that enjoy the LNR and Hy Endfed antennas, but want to run more power, Balun Designs now offers an excellent alternative. Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current matching unit or construct a new higher power end fed half wave antenna.
EFHW | Experimental Multiband Antenna with 49:1 UnUn. I made my first multiband experimental version of the Multiband EFHW antenna with 49:1 UnUn transformer. In this first part I want to show you complete process of made this antenna.
