QM7 7 elements 144 MHz Yagi-Uda Antenna
- The QM7 antenna is a simple 7 elements Yagi with 3.70 m boom length for the lower 144 MHz SSB/MGM band, used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 11.35 dBd; i.e. 13.5 dB forward gain over the isotropic radiator, while the F/R is about 12.5 dB
- The file MEI-10.ZIP contains educational software to evaluate antenna arrays of up to 8 elements. Two types of arrays may be studied: 2D planar arrays (Yagi-Uda, Circular, etc., up to 6 elements) and colinear arrays (up to 8 elements.)
