• 20 thru 10 Meter Fan Dipole - The 20 thru 10 meter dipole is constructed from stranded insulated wire available in most hardware stores. The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots used on lower frequencies.

• Fan Dipoles 10/15/20m and 12/17/30m - How to build Fan-Dipoles by DK7ZB. Experiences with various band combinations. Not all combinations are working properly. If the frequencies are to close together the impedances will lead to a very bad SWR. This happens with the bands 10-12-15m or 15-17-20m.

• 5 Band Telescopic Vertical Antenna - 5 Band 1/4 wave Telescopic Antenna. The 20m to 10m, antenna is simple and cheap to make, and has a performance that matches commercial antennas but at cost considerably lower. The design was purposely based on a telescoping fibre glass fishing rod as this allows it to be easily stowed away in the car.
