High gain 2.4GHz 11dBi directional antenna,panel,patch For Sale
Light-weight, small format factor, economical patch antenna. Pacman like circular patch pattern, looks more funny than the 14dBi at my other auctions. Back-side view: Front and side views: Very suitable to boost the wireless signal strength for small RF power fixed devices for wifi and non-wifi applications e.g. FPV, wireless A/V Tx, etc. Induce less interference and noise than active signal booster or high gain omnidirectional antenna. Using normal router to measure the signal strength, there is no significant numerical difference between 14dBi and 11dBi. Facing the antenna outside of my window, can discover many neighbors’ AP. Can hook up to some unencrypted APs stably. If the remote AP is not at the horizontal direction, e.g. downstair at 45 degree, and you can take off the internal connector of your gear and oriented the antenna appropriately. . Alternatively, you can take my another auction. Demo using 11 dbi antenna. Playing a clip from a remote NAS. Here is the demo of 2dbi rubberduck, for contrasting, pay attention to the flying owl. Can skip when you felt the stalling. Great performance to price ratio, with professional grade wireless link at very low cost. DIY building with mass produced key components.
