Building a Spiderbeam is really QUITE EASY, but there is a lot of repetitive work.  


As a result, it usually takes you about 20 to 25 hours to build the beam if you work slowly and double-check your work as you go.  


The Portable version takes a couple of hours more because you have to glue the Velcro strips onto the fiberglass spreaders and wait for them to dry.


The two steps which require a little bit caution and skill are:

  1. building the driven elements and feedlines
  2. building the balun.


Here are more detailed instructions for doing both:




This is  the MOST CRITICAL step in the assembly process:


Page 18, paragraph 3.1.1 :   Mounting the Vertical Mast.


This step the one that users get wrong the most often!



TO BE CONTINUED . . . .   I have to first make some drawings.
