Antenna inverted- V - tribander
Costruzione di un dipolo caricato per le tre bande alte delle HF 10 15 e 20 metri e siccome lo spazio a disposizione e' davvero poco, ho dovuto realizzare addirittura una "Inverted-V", appendendo l'antenna al centro ed ancorandola alle tegole, alle estremita,'pensandoci bene, e' anche un'antenna "mimetica", perche' e' travestita da tiranti per l'alto palo su cui svetta l'antenna TV.I materiali? Un tubo di PVC ad alta resistenza, del tipo per impianti idraulici ne servono poco meno di 50 cm e se non ve lo regalano costa pochissimo: un amico elettricista potra' fornirvi la trecciola di rame da almeno 2 mm di diametro un pezzetto di basetta per circuiti stampati, con il rame

Antenna Multibands Links →
15 Element Wire Log-Periodic 7 MHz - 30MHz TITANEX DLPD-15
Feeding with just a single coax cable for all seven bands 50 hm Loss-free linear loading feeding on 10MHz, full-size rotary dipole on 7MHz
40-10 Meter Antennas
All three dipoles were fed from a single 1:1 balun
6 band windom anten 80-40-20-17-12-10m, TA1CD
Our antenna will serve us for a long time if we isolate these parts from the external environment with hot silicone or similar materials after soldering the connections in honey. We can use our antenna in all hf bands except 160m, 30m and 15m
A dipole portable
Configured as a dipole, the ATX whips appeared not to be long enough.A loaded dipole is more efficient if the loading coil is closer to the top of the antenna
T2FD antenna Tilted Terminated Folded Dipole
