- 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.
