DP4001R
Weight:
1.20
kg
Assembled Version
This version is pre-assembled and ready to install on a Portable Version of a Spiderbeam Yagi. (Balun not included.)
The 40m dipole extends the coverage of most Spiderbeam Yagi Antennas to include the 40m band.
It may be added on to
most existing Spiderbeam Yagi antennas, or ordered together with a new
antenna. The dipole is rotated 90 degrees to the other wire elements.
Both sides of the boom are extended by one additional fiberglass tube, increasing the turning radius from 5 meters (16 ft.) to 6 meters (19.2 ft.).
Each end of the dipole is capacity-loaded using two wires tied back to the side spreaders.
