Reception help needed for 38313

[90chevy]

The two channels i want to pick up are WLMT and WREG. I get all the channels in green and i get WJKT in yellow. in the red i get WMC. a few days ago i added a pre-amp and now i also get WHBQ. also after the pre-amp was added WLMT and WREG come in on occasion at night. i have moved the antenna up and the reception gets worse. there is a large tree about 10 feet to the left of the line of sight. other than that its a clear shot southwest. I have no clue what brand the antenna is,it was here when i moved here. but,it is vhf/uhf. and i am just going to 1 tv via a dish network 722 receiver. http://www.tvfool.com/?option=com_wrapp ... 0d0eb2d38a
