Does anyone have details on this antenna, I assume it was made in the 60's . Embossed in the base are the words Hustler Cliff Dweller ,but no model number . It appears to be a 1/4 wave vertical ground plane . I have the base section and mounting bracket only , but can find no details of how long the vertical element should be and what bands it was intended for. Any help would be appreciated as I would like to repair this antenna.
