CAT-1 |
|
Applications: The CAT-1 antenna is intended to be used for signal gathering purposes in the 2-30 MHz frequency band. The principal function of the antenna is for reception of skywave and groundwave high frequency (HF) signals. A significant characteristic of the antenna is its polarization diversity, i.e. it is capable of HF skywave and groundwave signal reception, regardless of the transmitted signals polarization. The primary use of this antenna is for direction finding. Features: The CAT-1 antenna is a collocated array of three orthogonal dipoles and three orthogonal loops. Separate outputs for each antenna are available such that the user has optimum flexibility for combining the elements in custom configurations. Additionally, an external combiner that can be mounted to the mast of the CAT-1 antenna can be provided. This combiner provides variable signal gain through the use of attenuators and amplifiers. The single output consists of a single three dimensional cardioid pattern capable of detecting horizontally, vertically, and elliptically polarized radiation. Optional Equipment: Combiner assembly. |
