For those who do not have a Satellite system and still use their Winegard Sensar crank up Antennas, do you know to lube it twice a year or when cranking up or down becomes difficult? Winegard specifically suggests twice per year with a good silicone spray. Older manuals used to say don't use WD-40 as it would destroy the life of the gears, I would think that still applies. A few times per year when I am on the roof looking for seal voids and such, I bring a crescent type wrench and a can of silicone spray. Remove large black hex nut on top, spray a few blasts down the tube and also on the exposed gears. Replace nut. Go inside and crank up and down a few times to help distribute the silicone. Something to do to help make things easier to use and hopefully last longer without leaks down the shaft.
