![]() As you move along the wire the impedance changes. Moving the feedpoint to some other location could result your 9:1 balun being less efficient (mismatched). There are antennas which use a feedline connected to some point along the wire instead of the end but you have to make the connection at a specifc location, not just anywhere. The 'Windom' is one of these types. The following website shows the design of a basic Windom antenna. Note that the balun is 4:1 instead of your 9:1 for the end fed wire. This is because the impedance at the connection point for a Windom is lower than the end of a random wire or inverted-L. http://www.packetradio.com/windom.htm Thanks for the info. After doing research on the Windom antenna I gathered it was going to be a little more involved than I expected, and I'm not sure if it will be as effective for receiving. I'm leaning towards sticking with the random wire and just getting more coax to reach the feed point instead of bringing the lead-in closer. -Brian |
