EFHW Transformer

These are ~49:1, 56:1 75:1, or 81: ratio (~2500, 2800, 3750, or 4050:50 Ohms) UNUN transformers for EFHW antennas (End Fed Half Wave), just pick one and add half-wave long wire for the frequency of interest. The average insertion losses are unmatched by any other similar transformer on the market proving our worldwide leadership in the design of high ratio-wide bandwidth UNUN transformers. Note that it will also work on its harmonics for example 3.55 MHz x 2,3,4,5.6,7 and 8.
