I've had similar problems with the mast freezing in the sleeve... My solution was to make a cone-shaped guard and fasten it around the mast slightly above the sleeve opening (seal it well). It can be of sheet-metal although I used fairly stiff plastic sheet and heated it to form the cone. When done properly, any moisture (rain, snow, sleet) will be diverted away from the mast-sleeve junction and the mast will not freeze in the sleeve. You might want to apply some low temperature silicone grease to the mast, where it passes through the sleeve. Don't use ordinary grease because it is not capable of withstanding very low temperatures without getting stiff. If you have enough space between the mast and sleeve, a sheet of TEFLON can be used in place of the silicone grease. According to DuPont, TEFLON is the slipperiest material on Earth...<grin> By the way, if you can find a GIANT FUNNEL, you will have most of the shield right from the start...!
