Choosing this model
GL400Z5WS selection guide
GL400Z5WS is the shorter, lighter Yagi choice compared with GL401D. Consider it when the available mounting space or antenna weight matters more than selecting the higher listed gain.
GL401D trades a longer, heavier structure for higher gain and a narrower horizontal beam. Choose between them by the installation envelope and the required pointing width, rather than assuming that two models with the same operating range are equivalent.
