Terminated Sloping Wire
The CHA TD 2.0 Sloping Wire antenna, see figure (2), is a broadband short to medium range HF antenna.
It is designed to provide acceptable ground wave and sky wave propagation. This configuration is
predominately omnidirectional on lower frequencies, becoming more unidirectional towards the low
end of the antenna as the frequency increases. Positioning of the ground Counterpoise Wire also
produces directivity towards the end of the Counterpoise Wire on higher frequencies.
The Terminated Sloping Wire requires one support, is a good general-purpose antenna, and is excellent
for hasty deployment - when there is insufficient time or space for deployment of the Terminated
Inverted “V” antenna.
It should be raised to a height of around 25 feet for best performance. When
raised to 25 feet, the Terminated Sloping Wire antenna requires 55 feet of space for installation.
One Terminating Resistor Unit and one Antenna Wire are not used in this configuration.

Site Selection and Preparation.
1.
Perform

Assembly procedure, if needed.
2.
Select a site to deploy the CHA TD 2.0
Sloping Wire antenna, see figure (2). The
best site should have a tree or other
support that would enable the Terminating
