My ChannelMaster 4228 is behind our house on my shed.  The shed is a little bit down hill from the house so I think that the house may be blocking some of the signal.  I have it on a 5' mast which with the shed it is about 12' off the ground.  If I put it on a 10' mast, is it possible that I will get a better signal?  Can I just got to Home Depot and get a steel pole and use that?  There are virtually no stores in my area that even carry such an item.  I can use two 5' poles but I would rather use one 10' for strength.  Any thoughts?
