Portable UHF 4 elements Yagi Antenna
The antenna has 7.5 dBd (9.6 dBi) gain at 436 Mhz and the SWR varies from 1.3 at the lower edge, almoust to 1.05 to midband, and 1.9 at 440 Mhz
Magnetic Loop Antenne 70cm
The consequence: I'm mostly qrv on the vhf/uhf bands or on the higher hf bands - with easy to move self-made antennas and low power
