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. You will find suitable aluminium masts here.

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 700 spiderbeams are already installed worldwide.
