 The 160 meter dipole is constructed from #12 stranded insulated wire the feedpoint uses a section of pvc pipe, the ladder line loops through the pvc pipe to provide strain relief |
The capacitor will help raise the radiation resistance at the feed point, for permanent use, we would adjust the value of the capacitor as well as L2 until we optimized the match |
 Double Half Delta pressappoco come una Beverage. L' antenna è costituita da due triangoli di filo sospesi a un metro e mezzo da terra |
