 For sale are a set of five (5) unused mil-spec RF transformers manufactured by Lorch Electronics.   These were surplused from a defense contractor.   They are encapsulated in a tin-plated steel case and are useable up to 30 MHz.   From 10-30 MHz there are resonant peaks and dips so they are not really broadband.   They would useful for building RF return loss bridges or for other HF experiments.   The last 2 pics show a test with 30 MHz input.   On the scope pic the upper trace is the input (signal generator side) and the lower the output, which is terminated in 50 Ohms.     Above 30 MHz the response falls off a lot.  Combined shipping offered.   Purchase multiple items individually and a refund for the excess shipping charge will be issued.
