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

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.

- building the driven elements and feedlines
- building the balun.
Here are more detailed instructions for doing both:
