CHOOSING A LOCATION FOR THE ANTENNA
The best performance on receiving and transmitting will be obtained by mounting the antenna in
a clear location above or away from buildings, towers, feedlines, utility wires, and other
antennas. While your own ingenuity and particular circumstances will determine the final
mounting method, we'll pass along a few ideas for both permanent installation and portable
operation.
Warning: Always mount this antenna so that it is out of the reach of adults as well as
children. The capacitance elements can cause injury and or severe RF burns.
••••
Never mount this antenna in a location that will permit unsuspecting people to come in
contact with the loading spokes or any other part of the antenna.
••••
Never mount this antenna where a mechanical failure might allow the antenna to contact
power lines or other utility wires.
••••
Always ground the feedline at the point where it enters a building to a good earth ground for
lightning protection.
•
Always follow the guide lines for antenna installations as recommended by the US consumer
product safety commission.
Permanent Installation
The ideal installation is a rigid pole or roof mount that puts the antenna completely in the clear.
If the ideal installation is not possible, choose the best compromise. TV mast or steel water pipe
are suitable mast materials. This antenna will mount on masts between 1 and 1-1/2" OD. The
use of soft or thin wall masts is not recommended. Never use mast made of soft material or thin
wall aluminum, such as aluminum tubing and conduit.
The VEC-896 will perform quite well even at ground level, which means the lower capacitance
hat should be at least 5 ft above ground level on a short rigid mast. However, the antenna
installation MUST be protected (with non-metallic fencing) to provide personal safety and to
prevent damage to the antenna itself.
Portable Operation
This antenna may be disassembled to the extent necessary for transporting to a temporary
location. If possible, only remove the two HF loading coil assemblies. Leave the two main
elements with the 2 and 6 meter stub assemblies intact. Some retuning may be required after
moving the antenna.
Note: Even for temporary or portable operation, do not be casual about selecting a suitable
mast. If the antenna falls it will be damaged and may cause serious injury. Whatever
type of installation you choose, remember that the antenna should be installed where it
can never be contacted by people or animals.
