My boyfriend rigged this up for me last summer. 4 Ratchet straps, (700lbs each strap) secured from my ceiling joist by galvanized metal T-type "T & L Strap Ties". The top part of the T was attached to the joist above the drywall and then a thin slit cut in through the ceiling for the bottom of T part to slide neatly through which holds the hook of the strap. All for an extremely low price of $35.00 canadian. Once I shut off the camera I neatly wrapped up the hanging cords and zap strapped them up.
The clanking sound you hear when I drove in is the aerial hitting the top. I have since raised the roof a tad higher to compensate.
