- QM5 Yagi for 2 meters band
- The QM5 antenna is a simple 5 elements Yagi with 1.88 m boom length for the lower 144 MHz SSB/MGM band, I used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 9.17 dBd; i.e. 11.3 dB forward gain over the isotropic radiator, while the F/R is about 11.5 dB. Elements

- The 5 Bands Wire-Beam
- This wire-beam has one radiator-element, feeded with 450-Ohm-Wireman-twinlead and needs an antenna-tuner. For the bands 6m, 10m, 12m, 15m, 17m and 20m bended reflector-elements are used.
The support is a cross of 4 fibreglass-fishing-rods
