Significant cost savings
Large antennas and tall-antenna supporting structures are not needed for the EH antenna to work, nor are there any concerns about nearby metallic structures. The space required for the EH antenna is minimal. Because the antenna works so well in all directions, directivity in installation also is not a concern. A normal Hertz antenna has nulls in the radiation pattern, and a power amplifier sometimes is used to overcome these nulls. With the EH antenna, powerful amplifiers and their associated power supplies are not needed, as there are no nulls in the EH antenna’s pattern. The unique design of the EH antenna allows the antenna tuner to be powered from the exiting coax feeding the antenna, eliminating additional wiring or retrofit of cabling.
Further, talented electronics technicians and engineers, expensive installations, and books on antenna theory are not required for installation. As a result, the amount of money that can be saved on an EH antenna installation, compared with other options, can be significant, as follows:
Tower…………………. $4,000 to $250,000
Rotator………………………. $500 to $2,500
Power
amplifier …………….. $2,000 to $5,000
Book on antenna
theory ……………………….. $30 to $200
In conclusion, the EH antenna has so many significant advantages that it is the ideal antenna for fixed, portable, mobile and rapid-response emergency communications applications. It requires a small amount of physical space; this is important because it can be installed in areas that require zoning permits or have zoning, deed, and other restrictions that prohibit the erection of the towers required for conventional antennas to perform correctly on the HF bands. It also works well without a tower, rotator or power amplifier; and one does not need an engineering degree to install it.
In short, the perfect antenna has been invented and it is available for use right now—visit www.AlphaCognetics.com for more information.
