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

Hybrid Balun 1:2 (25 Ω to 50Ω)  1- 30MHZ  1KW which consists of a unun 1 :2 RF transformer (25 Ω unbalanced to 50 Ω unbalanced) followed by a common-mode choke 1 :1 (25 Ω balanced to 25 Ω unbalanced). incorporates for higher feedline isolation and RF choking.   This unit balun (balanced 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 30MHz.  The efficiency is 99 percent       Technical specification: Type:                                               1:2 unun Frequency:                                      1MHz – 30MHz Input Impedance:                             50Ω Output Impedance:                           25Ω Typical insertion loss:                       less than 0.15 dB Power Handling(CW/SSB):             800W /1KW and 2KW of peak power Core Type:                                      FT240-43 by Fair-rite® Co.
