I wanted a bit more “oomph” from my 1W 1.2 GHz HT, so I purchased a PC board Yagi to get another 6 dB.
I have a Yaesu FT-911 1.2 GHz HT. It is a 1990’s rig gifted me by the wife of a Silent Key at my work. It is a sweet handheld, but with limited power.
WA5VJB makes a variety of PC board antennas. The 1.2 GHz 3-element Yagi is $6, which was hard to resist. He also makes other nice microwave antennas: log-periodics, patch arrays, wheels, vivaldis, etc.
