It is important that you do an inventory of the items that were shipped to you. Nothing is worse than
discovering a day before a planned installation that there are missing parts! We do our very best to en-
sure that you receive everything needed for construction of your antenna, but better to be safe than
sorry—inventory your parts well in advance of your installation. The items in blue represent options
available for the DB18 Yagi—you will need to check these items off only if you purchased them.
