1112-web-picModel LP-1112MR is a lightweight transportable and rotatable log periodic antenna system covering the frequency range of 4 through 30 MHz. It is designed for temporary or permanent installation with minimum deployment time. This unique antenna incorporates an extremely small size considering the frequency coverage of 4 through 30 MHz. The antenna dimensions are only 87 by 62 feet with a tower height of 60 feet. The net weight of the system uncrated is 2,000 pounds. Rotation is accomplished through the use of a mechanical stop and halyard device, eliminating the necessity for electric power of any kind during system erection and operation. Installation and erection can be performed by a crew of six men in less than four hours. All installation tools and fixtures are included in the antenna kit.
