Minibeam Geometry Basics
There is a natural progression of the geometry of the mini-beams deriving from the basic yagi, which in itself owes a lot to the common dipole

Combi-dipole for 30 and 40m
After some experiments I could dip the trap around 10 MHz with a coax capacitor (17cm of RG214) of 17pF. So the coil at 10 MHz has an inductance of 14.7 µH at 10 MHz
Dalle VHF alle HF
Questa antenna per HF e' stata realizzata in un materiale poco usuale, cioe' tubi in plastica rivestiti di foglio d'alluminio
Dismantable Yagi for the bands 10-17m
The distances between Reflector-Radiator and Radiator-Director are the same on all bands from 10 to 17m. When changing the band you only have to adjust the element-lengths
