End Fed Half Wave Transformer with KX2

This video from Waters & Stanton Ltd demonstrates their Hi-Match XFL RF transformer for feeding an end fed half wave antenna. The demonstration shows how it can be used with a KX2 or indeed any transceiver up to 100W.

Thanks for the info, Peter.

Ed, nice to hear from you. 73s Peter

Will this transformer resonate part of the signal and consume some of the power? I am not referring to tiny parasitic resistance loses of the windings. I am referring to actual LC resonance of a tank circuit with significant power losses at the antenna.

Unable to find it on the W&S website after a while of searching. Why don’t you add a link in the description? Thank you, 73

Is the Hi-Match XFL available?

Hi Ed,
I decided not to make it commercially as I do not have the facilities myself. I have an eye problem so would need to job it out. But appreciate the enquiry. 73s Peter.

@@watersstanton can you give us a clue how to make one? A video perhaps?
