I would say in 99% of cases if not more, getting the antenna outside will help.
But there are a lot of constraints to that. If your balcony is on the opposite from where the TV are located, it might be futile. If you buy the wrong antenna it will be futile.
Best thing to do is post your TVFool plot and let us analyze it and give you suggestions.
Go to
http://www.tvfool.com/?option=com_wrapper&Itemid=29 put in your address and if you live on the ground floor put in say 5 feet for your antenna, but add 10 ft for each story above the ground floor is you live higher.
Then copy the bold type link at the top of the results page and paste it back here.
