Long wire antenna
Description
The long wire antenna is suitable for multi-frequency operation using an antenna tuner
in most transceiver systems. It is approximately 20 m (22 yd) in length.
Where used
The long wire antenna is used on buildings or open ground. It is ideal for field crews
who require an antenna that can be quickly and easily installed at temporary sites. It
may also be used in permanent installations where space is limited.
Installation
The long wire antenna is designed for permanent or temporary fixed station
installations. It requires at least one mast and sufficient space for installation.
Advantages and limitations
Table 45: Advantages and limitations of the long wire antenna
Advantages Limitations
Wide range of operating frequencies.
Large in size, therefore, is more
efficient.
Must be positioned at right angles to the
desired direction of communication.
Due to its large size, it requires a large
area for installation.
The length of the wire may be too long
for some operating frequencies and
tuners. Under these conditions, the
length of the wire must be reduced
according to the recommendations
provided in the handbook for the tuner.
