HB9CV+3 for 431 and 435MHz
The HB9CV+3 is a fullfeeded directional antenna with 2 active plus 3 passive elements. One might call this array "HB9CV-Yagi". This adds about 3dBd over a pure HB9CV and eliminates the squint of the classical 2-element HB9CV

3 Stacked Yagi Antennas
The use of three antennas often represents a good compromise between increased antenna gain, mechanical feasibility, and satisfactory handleability
432Mhz Quagi,
This Quagi is optimized for 432.2Mhz operation, however it works well in a quite wide range of frequency
5 Element-Yagi fur 145 MHz
Boom Length 1705 mm, Elements diameter 8-10 mm, hollow material they are obstructed by the boom, adjustment stub range length from the central arm to the collection clamp 175-200 mm diameter of aluminum tube from 6 mm distance between stub and radiator 15 mm
10 Element for 432 MHz Winkler Antennen
The elements have direct connection to the supporting boom by a metal ring where on either side one half of the element is screwed
70cm 10-element uhf yagi
Adjust lenght of the dipole if needed important,you can also use a folded dipole with a 1:4 balun
