DX Engineering Dual Impedance Antenna Transformers are dual ratio UNUN (unbalanced to unbalanced) transformers. They're great for coupling your 50 ohm coax to an antenna with a feed point impedance of either 25 or 12.5 ohms, typically found at HF mobile antennas. DX Engineering Dual Impedance Antenna Transformers are ideal for antennas that have been enhanced with a Hot Rodz capacity hat. These units are housed in an aluminum enclosure and use silver plated PTFE SO-239 connectors.
Power handling capability depends on the match:
* Using the 25 ohm to 50 ohm port, with SWR below 2:1 on the 50 ohm side, -- 750 watts PEP
* Using the 12.5 ohm to 50 ohm port, with SWR below 2:1 on the 50 ohm side, -- 500 watts PEP
