I have learned a lot here and just got my account verified. I would like to get a recommendation for an antenna setup. Currently I have a Radio Shack directional antenna as below on a ground mast 20ft high and a CM-7777 mounted just below the antenna. The major problem is a number of large fir trees all around the area. Most of those north-northeast are 200-400 yards away on a hill about 20-40ft higher than my location. Presently I get many of the channels I want up to 33 but the reception is very spotty. Some days everything comes in decently, some days very little comes in without breaking up sporadically. Rotating the antenna 30 deg between north and northeast helps a bit for individual channels. I plan on mounting an antenna permanently on the roof as soon as I settle on the right one and my height will increase about 20ft. I would rather not use a rotator if possible.
Here is my map.
I very much appreciate any help.
