looks like an old bullwhip/hustler/valor/modulator style rip off. theres been hundreds like it, all work reasonably well for their low cost. usually handle a couple of hundred watts and give decent swr across about 100+ channels, whips are generally about 48" long or thereabouts. just a basic base loaded 1/4 wave, no more no less, ideal back up to carry should your main twig fail.
