I've had a problem testing my wifi equipment, it has just been laying on the table.
But i wanted to mount it for testing, but the problem of building something (and not having the tools) i was forced to think of another solution.
And this is what i came up with...
A Stripper/Dance-Pole Like this:
The one i got for about €45 that can be mounted anywhere between the floor and the ceiling, no screws needed and look's nice in the office.
Right now i have 2x ubiquiti rocket's with the mimo dish mounted and also some loco's as CPE and a RB333 as AP in my homemade case.
