Antenne-long-wire-balun-9.1

Wire & Random Antenna Links

127



Wire Dipole for 7.05 MHz
The dipole is mounted with its centre over the top of my new tower. The top is 11.5m

Type Levy ou center feed
This 1/4 balun operates in voltage. It is made by winding a toroid of iron powder about ten turns of a two-wire line twisted in 15 / 10mm wire

Antenna Vertical Sloper 40/80mt
L'antenna e' alimentata con cavo RG8, NON HA bisogno di adattatore di impedenza


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band

Rx antennas 4Square Rx Vertical Array
