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

Portable Yagi for 144MHz - Simple 7 element Yagi is ideal for portable operation.

Understanding Standing Wave Ratios SWR - We worry a lot about Standing Wave Ratio (SWR) in amateur radio since SWR is one indication of how well our antenna system is working. Most HF transceivers and antenna tuners have built in SWR meters. SWR is a measure of a transceiver’s output power verses the portion of that power reflected by the antenna system By Ken Larson KJ6RZ

9 band vertical HF antenna by RW3XA  ^pop - Simple vertical radiator with matching box. No traps, no tuner required.

Half square antenna - The elevated half square antenna is a very simple antenna that can be constructed from common materials yet gives significant improvement over a dipole at the same elevation. Ground mounted versions of this antenna are commonly used in amateur radio for 75/80 and 160 meter bands
