Design catalog

Every built-in design is an AntennaBuilder whose source is meant to be read and copied. Address them as family.name (the same names python -m antennaknobs list prints), and open any in the live simulator to drag its knobs. Many are modelled after L. B. Cebik (W4RNL)‘s articles.

Dipoles

Design	Notes
`dipoles.invvee`	Inverted-vee dipole (the default quickstart example)
`dipoles.folded_invvee`	Folded inverted-vee
`dipoles.ocf_dipole`	Off-center-fed dipole (Windom) — a half-wave fed away from the middle
`dipoles.dipole_turnstile`	Crossed dipoles fed in phase quadrature
`dipoles.koch_dipole`	Koch fractal dipole
`dipoles.short_dipole_loaded`	Center-loaded shortened dipole (a Load-branch showcase)

Loops

The delta loop is the catalog’s teaching showpiece — one loop laid out four ways, all exposing the same knobs (base, length_factor, angle_deg) and producing byte-identical wires. They differ only in how you specify the geometry, from writing every corner as coordinates to flying the whole shape with a Drone (see Many ways to express geometry):

Design	Built by
`loops.delta_loop`	the shipped version: corner coordinates from a closed-form expression for the top corner
`loops.delta_loop_flyby`	full `Drone` (3D turtle) flyby; top laid by `forward_through_plane`, feed-anchored with a z-offset pass
`loops.delta_loop_reflected`	`Drone` point-finder + `ry` reflection + `build_path` (side solved for the perimeter)
`loops.delta_loop_topdown`	top-down flight: starts at the top, `forward_to_plane` lands the feed where the slant crosses `y = eps`

Other loops: loops.delta_loop_slanted, loops.inv_delta_loop, loops.horizontal_loop (full-wave “loop skywire”) and its Drone twin loops.horizontal_loop_drone, loops.diamond_loop (+ diamond_loop_turnstile), loops.quad (2-element cubical quad beam), and loops.bisquare (a two-wavelength broadside curtain).

Beams

Design	Notes
`beams.yagi`	Yagi–Uda parasitic beam
`beams.moxon`	Moxon rectangle
`beams.hexbeam`	Hex beam
`beams.hb9cv`	ZL-Special / HB9CV — a 2-element all-driven phased beam

Verticals

Design	Notes
`verticals.vertical`	Quarter-wave vertical
`verticals.raised_vertical`	Elevated vertical
`verticals.inverted_l`	Inverted-L, a bent top-loaded vertical
`verticals.jpole`	J-pole, end-fed half-wave with a quarter-wave matching stub
`verticals.half_square`	Half-square, a vertically-polarised wire antenna
