and each approximately 12 feet long and sloping downwards at 45 degrees, is probably the greatest amount
of loading that can be used for coverage of the entire 40 meter band with acceptable SWR, even if all the
turns of the 40 meter coil are shorted out. With this particular top-loading arrangement the 80/75 meter
bandwidth between the 2:1 SWR points should be nearly 100 kHz.
If one is willing to sacrifice 40 meter operation for the sake of even greater operating bandwidth and greater
efficiency on the lower bands the "umbrella" wires can be lengthened considerably. Four 25-foot "umbrella"
wires, for example, would provide some 125 kHz of operating bandwidth on 80/75 meters.
Top-loading wires should not be attached to the very tip of the antenna because the tubing in the two
uppermost sections is no stronger than it needs to be to support itself. Operation of the HF2V may be
extended to the other bands through the addition of accessories without sacrificing 80 and 40 meter
performance.
