Trapped dipole for 80 and 40 m
- This article explores a theoretical model for the losses of an 80m / 40m trapped inverted V dipole antenna system using a bootstrap coax trap, but does not examine the pattern of the antenna.
HexBeam for 6 meters
- This is a hexbeam designed for six meters. It has three elements with a turning radius of 54 inches. This antenna can be built from low cost materials available from the local hardware store. By WB3BEL

Vertical antenna for Vacation
- Vertical Vacation Antenna for 80, 40 and 20 Meter-Band, by Herbert OE3BMB
This antenna is a full size λ/4 for 20m and 40m band, and a shortened λ/4 for the 80m band.
Generally on the 40m band the SWR is under 1,6. In 80m and 20m band at the resonant frequency the SWR is about 1,1.
