 Soldering the elements. Pay attention to the
wet piece of kitchen paper placed near the plastic pipe to prevent it from
melting due to the high temperature generated at the soldering point.

 The plastic cover placed on the top end of
the plastic pipe with the 4 holes placed 90 degrees apart each other. This
cover is used to house the 4-turn RG-58 balun and prevents rain and sun to
come in contact with the balun.
