The normal-mode helix antenna
A helix will work in the normal mode when the diameter and pitch of the helix is less than 0.1 Lambda When working in this mode the radiation is from the side of the helix, and when the diameter is considerably less than 0.1? the resultant 'spring' has a radiation pattern similar to a short vertical monopole or whip

La pounder de 144 MHz
La QUAGI 144mhz 1200 antenne miracle
Piccola HB9 per VHF
Semplice collineare per i 145 Mhz
147
La pounder de 144 MHz- the pounder is a directional antenna for the 2-meter band, which provides a theoretical gain of 7.2 dBi and an F / B of over 20 dB
La QUAGI 144mhz 1200 antenne miracle- An 8-element quad antenna is tedious to build, the tiles being awkward to fix on the boom and to manufacture, on the other hand, from 3 or 4 elements, the difference between the quad and yagi fades
Piccola HB9 per VHF- Questa antenna costruita secondo la filosofia della HB9CV è stata sviluppata con il programma di simulazione AO 6.58 è molto efficace ed è la più piccola HB9 esistente per VHF
Semplice collineare per i 145 Mhz- La taratura dell'antenna e semplice, basta spostare i collarini avanti o indietro a seconda delle misurazioni del rosmetro
