Line Launcher - The line launcher is a handy tool which is a must-have for anyone who uses wire antennas. It provides an easy way to mount the end of a wire antenna up into a tree. It basically consists of a fishing reel mounted to a slingshot, which is a tried & true design.

W5GI Mystery Antenna  ^pop - W5GI Mystery Antenna is a multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It�s similar to a G5RV but a much better performer especially on 20 meters.
