New Low-Profile AM Antenna Ready for U.S. Sale

In October, as previously reported here, the FCC simplified application procedures for construction permits that specify non-directional KinStar antennas. Now the backers of this low-profile antenna system are ready to sell it in this country.
Star-H Corp. and Kintronic Laboratories developed the antenna for areas with zoning tower height restrictions.
“The low-profile antenna affords users the flexibility to place antennas in areas where taller towers may be unacceptable, such as in close proximity to airports or in metropolitan areas where zoning ordinances limit the height of new structures,” stated Tom King, president of Kintronic.
The backers say the KinStar antenna offers a radiating efficiency that is 98% that of a quarter-wave tower but with a vertical height 67% less than that of the quarter-wave tower, and a wide bandwidth compatible with IBOC or DRM digital audio broadcasting transmitters.
Based on its review of KinStar field tests and submitted reports, the FCC won’t routinely require submission of proof of performance, current distribution measurements or a formula for the vertical plane radiation characteristic for non-directional AM stations that implement KinStar antennas.
The developer tests show the KinStar antenna meets minimum efficiency for Class B, C and D stations, according to King. Applicants may only specify the KinStar antenna for nondirectional use.
