make potato-sized solder joints when assembling the antenna. So, I

wondering what would be the best way to connect various parts of the
antenna?

Thanks to everyone who gave advice; very helpful.

The person who stated that "high ohmic connections" were deleterious to
QRP ops was describing his construction of a linear loaded dipole and
the connections to the inductance section of the antenna (see N5ESE's
article on the "Notebook antenna"
http://www.io.com/~n5fc/notebk_ant.htm). This is a small radiation
resistance antenna and could be affected by bad connections.

The balun's connections, described in my original post, will not be
subject to mechanical stress 'cuz it will be bolted down inside a
connection box and protected from the wx.

Thanks & 73
