It is important that you do an inventory of the items that were shipped to you. Nothing is worse than dis-
covering a day before a planned installation that there are missing parts! We do our very best to ensure 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 available options — you will need
to check these items off only if you purchased them.
