** Warning message of choosing how long cable
===================================
i) The rule is KEEP IT AS SHORT AS POSSIBLE because there is problem of SIGNAL LOSS in cable transmission.
ii) Longer cable = More signal loss = More dbi loss!
~ so extending antenna cable should be LAST WAY after you try following:
i) if use with usb wifi adapter, get usb extension cable first.
ii) if use with access point / router, use power extension or POE LAN cable first.

*** Adjustable up/down tilt mounting kit
=============================

AMY yagi features an up / down adjustable mounting kit. This is important because 18dbi got narrow coverage area, user must focus it sharply to the signal source, so this adjustable tilt mounting is key important to yagi usage.

Best use for:
=========
1) with wifi adapter to get long distance signal.
2) with router or access point to work in repeater mode / wireless point-to-point bridging / receive signal in wireless client router mode, etc.
