The portable Spiderbeam is a DXpeditioner's dream antenna. It is a fullsize 3-band yagi, consisting of 3 interlaced
monobanders, in a lightweight and durable construction made of fiberglass and wire. All parts are made from high quality
materials resistant to weather, UV rays and corrosion.
This antenna is recommended for temporary use during field days, expeditions, contests, travel and installation in special locations for a limited period of time. For permanent installation, we recommend the more robust HD (heavy duty) version.
This 3-band version is an excellent choice for the low sunspot years, when 12m and 10m might be closed most of the time. The
performance on 17m is enhanced by integrating an additional director element.
Putting together this antenna kit will be a fun and educational project. It contains all the necessary parts to make a 100%
complete antenna (exactly as described in the construction guide - including some prefabricated parts). Nothing beats the
satisfaction of cracking pile-ups with an antenna you built with your own hands!
Welcome aboard. Over 1000 Spiderbeams are already installed worldwide.
