dear friend
a dipole antenna is not so wideband for covering 0.7-3 GHz. you may design a striped log periodic antenna.
pay attention that the equivalent diameter is half of the strip width. you may slim strips for being constant k.
if you use PCB , add its EPSILON AR on your calculation. good...
dear friend
on your design you have toe , sigma and R........toe 0.8-0.95 sigma 0.05-0.2 R 50 or 75 ohms
first- calculate za =60 ln{ (16 k toe sigma)/[pi (1+toe)]}
k is average ratio of elements LENGTH to DIAMETER.for better resault you may slim elements to be constant k.
ln is...
dear friend
reception tv channels from air has some conditions.

tv transmitter's antenna,you should risen the hight of your antenna or relocate it
