The Simple Broadband Antenna was designed on base of my local environment
and taking into account the ease/cheap
to do. Figure 1 shows the antenna. Three points
there are need to install the antenna. There is one point at right
fence second point at left fence and third point at a window on
the second floor of my house. For antenna wire it
was used electrical copper wire in diameter 18- AWG in strong
black insulation (33-cent/m, Home Depot is supplier).
Antenna is simple to do. A 10- meters length of the
wire is fastened by the ends to both fences. Leave 50- 80 cm free
wire length at both sides at initial installation.
Figure 2 shows the wires. The length, from one side, should be used for tuning
antenna in to the resonance, at second side should connect with
feed line. Center of the wire is heightened and attached to the
Ground of the antenna included a wire going on to the
fence down to the earth. Near the earth the wire was connected
to an earth wire. The earth wire was made of three wires. One
wire was galvanized bare wire in 18 AWG. Two wires (similar to
the antenna wire) were attached to the stranded wire by ties.
The triple wire had length near 3.5 meter.
