4 basic Antenna Patterns – Donut Dipole, Omni Vertical, Directional Yagi & EFHW

In this educational part 2 of an antenna series video (likely from a ham radio YouTube channel like Tank Radio or similar), host Frank discusses radiation patterns of four basic antenna types—dipole, vertical, Yagi, and end-fed halfwave (EFHW/inverted fed halfwave)—using free MMANA-GAL antenna modeling software (moment method tool based on MININEC, great for beginners with plenty of tutorials). Guest Paul @PrepHamPaul joins to demonstrate live models in free-space or near-ground setups at 20m/14.05 MHz, showing the classic broadside "donut" pattern for a horizontal dipole (perpendicular to the wire, directional when oriented properly), omnidirectional 360° donut for a vertical (ideal for all-around coverage like Field Day), highly forward-focused lobe with strong nulls behind for a multi-element Yagi (great for DX, satellites, moonbounce, or fox hunting with elements like reflector, driven, and directors), and a sloped EFHW's "gumdrop" high-angle pattern biased toward the downward slope (popular for POTA due to easy setup, tree support, minimal space, and good local/regional performance with a short counterpoise).
