Hello, I'm looking to build a Step-down balun 12.5-50ohm ie input with 50ohm coax and output to 12.5ohm wire. Can any one point me in the right direction for a plan. I know they exist I've seen them

both of those are 2:1 turns ratio. You just need to flip it around. For your application, the coax (50 ohm side) goes to the winding with more turns. _______________________________________________ _

Just flipping the balun might not work as the Hi-Z side is balanced and the Lo-Z side is unbalanced. Just the reverse of what he probably needs. 73 de Perry - K4PWO __________________________________

Hi, Yes exactly, I'm looking for 50ohm unbalanced to 12.5ohm balanced. Thanks Robert G0HGW (ps sorry I can't how to reply to a message) Message: 11 Date: Thu, 20 Aug 2009 13:57:58 -0500 From: "Perry

Robert, If you are looking to have the balun built got to: http://www.balundesigns.com/servlet/StoreFront He can build anything you want reasonably. I have no pecuniary interest in the company, just

He builds very high quality stuff, I have a few of his things.. Give him a call to discuss what you want, he takes all the time to ensure you get what you want. He makes all items himself and winds h

It's the circuit, including the antenna and transmission line and coupling to surrounding objects that makes an antenna balanced or not. A balun does not do that. I suggest that you (and the original

True, but flipping the balun would unbalance the intended balanced side due to the ground reference point. I said "might not" because I didn't know his antenna feedpoint configuration. My pet peeve i
