For my backpacking rig I think I can do my own impedance matching, but at some point I'd like to downgrade my LDG Z-100pro to a manual tuner, such as: * [ZM-4|http://www.qrpproject.de/UK/ZM4.html] * [VU2RM's|http://www.qsl.net/vu2upx/Projects/antenna_tunner.htm] * [KC8AON's Junkbox|http://www.angelfire.com/electronic2/qrp/minit.html] * [K7SFN's 2-variable-component|http://www.k7sfn.com/projects/tuner.html] * [Cebik(SK)'s Antenna Site|http://www.cebik.com/content/index.htm] - Requires registration, but one article starts out like this, "Non 'antenna' people can’t fathom what it is that fascinates us with these metal antlers."
