Here's how I put my wifi antennna...
Antenna up using a Shakespeare 'boat' mount
Antenna down for moving, I added the 'rest' to keep it from 'flopping'
and how it looks with a side view of TT
This antenna (the coax run 'what a bear' in the ceiling) is connected to my JEFA Tech repeater and went from 2 wifi signals to 10 wifi signals with the antenna... works real good.. See my Post about ASUS RT-AC66U as a repeater in this forum, I'll be posting the results of the antenna on that router set as a repeater... All kinds of ways to get wifi and it's not that much money to 'get the good stuff'..
