- 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.

- The EZ-Tuner
- The "EZ-Tuner" is a homebrew automatic legal-limit antenna tuner that covers all amateur HF bands from 160-10 meters. Using a T-network design and controlled by a BASIC Stamp BS2sx microcontroller, the EZ-Tuner will match at least a 16:1 VSWR for either unbalanced or balanced transmission lines.
