Abstract:

A supplemental device is provided for mounting on a rod-type antenna for CB radio, cellular telephone, telephone, television and satellite communications for reducing the overall noise level in connection with the operation of, for example, the squelch control structure of the associated radio apparatus. The device comprises a pair of assemblies each having at least one ring and a plurality of cooperable radially-extending rods symmetrically arranged and intersecting the axis of the associated ring or rings, with such rings and rods secured in rigid relation any lying in substantially a common plane. The assemblies are disposed in spaced parallel planes and rigidly connected substantially of their common axis by a cross member which is adapted for adjustable securement to an antenna, whereby the supplemental device may be secured to the antenna at an optimum location therealong, with the antenna extending in a plane parallel to and between the first-mentioned planes. A spring element may be slidably mounted on the antenna rod for further tuning with respect to sensitivity and noise. The rings, rods and spring element are made of a chrome-platable plastic, such as ABS plastic, and are plated with chrome.
