Hi Bill Got one last year to use on a vertical in conjunction with a standard tuner and now as a conterpoise to a LW antenna. It resolved effectively a high SWR problem I had.
It consists of a LC network which creates a low impedance path to a standard ground. An L and C network don't create a ground; it rather makes a poor ground more effective. Will send you a schematic of the MFJ 931 via email. If anyone else is interrested, let me know. 72/73 de Pierre KX1 #442 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
