FL Antenna Advice Request - TV Fool Link

[groven]

Trying to grab the Yellow and Green channels in the 254-255 True range and 175-178 True range on the TVFool link here: http://www.tvfool.com/?option=com_wrapp ... 09bcbc3132

All except two show up as Green "Indoor antenna receivable", two are yellow "attic antenna receivable" (in theory!). Here are my pertinents:

-Single story home with heavy vegetation for a mile radius, but vegetation is no higher than mid-roof height.
-Frame construction with wood siding, but a metal over plywood roof.
-Limiting myself to an in-attic solution for aesthetic reasons combined with a personal compulsion to avoid any foot traffic on my roof.
-If the ideal solution is directional, I can aim an attic antenna through a 3' x 15' Hardie Plank over plywood gable towards the 175-178 towers, however my line of site will just be clipped by the neighbor's two story home.
-Single TV, Samsung LCD
-I have tried rabbit ears and was able to receive just less than half of the "green band" stations.

Thanks in advance!
