FT240-43 1:2 UNUN (25 TO 50 OHMS) 2KW EN FRANCE

This unit unun (unbalanced to unbalanced) transmission line transformer  designed to match 25Ω  to 50Ω used to match inverted L's,Yagi 20-25 Ohm driven elements directly without the need for matching networks, like gamma, T-match, or hairpin matching and other  unbalanced  antennas with low feedpoint impedance. Thus the currents are distributed more evenly about the conductors.  The power rating is 1KW of continuous power and 2KW of peak power.  It has a constant impedance transformation ratio of 1:2 from 1MHz to 54MHz.  The efficiency is 99 percent       Technical specification: Type:                                               1:2 unun Frequency:                                      1MHz – 54MHz Input Impedance:                             50Ω Output Impedance:                           25Ω Typical insertion loss:                       less than 0.15 dB Power Handling(CW/SSB):             1KW /2KW and 3KW of peak power Core Type:                                      FT240-43 by Fair-rite® Co. Wire type:                                           Coaxial cable  by Filotex®    Insulation type:                                PTFE   Performance See Performance Plots   Package Contents You get what you see. FT240-43 core by Fair-rite® winding with  Coaxial cable  by Filotex ®    Assembled and tested.   This transformer requires a feed line choke to isolate the coax feed line from the antenna.   SHIPPING We ship worldwide from French by Registered Air mail with tracking number.
