Vertical HF multiband antenna V8
Height 6,5m Impedance in point of power supply 50 Ohm SWR 1.5:1 or less Power limit: 1000W Bandwidth at 2:1 SWR and less ? on 10M, 12M, 15M, 17M, 20M, 30M and 40M - whole band on 80M - 80 kHz

Verticale per 14 mhz
La bobina dicarico e'costituita con un filo di rame, 9 spire del diametro di 0,8

Verticale per i 40 - 17 metri
I risultati migliori si ottengono con un buon piano di terra formato da 10 o meglio 20 radiali

HF Exponential Cage Antenna
Wire skeleton structure with 8 vertical wires
