It is tedious rooting out which of the many translator stations all around you carry which networks are around you.
It appears that at 306-308 degrees and 23 miles you have ABC on RF5 @4.1; CBS on RF7 @2.1; FOX on RF9 @ 28.1; NBC on RF3 @ 6.1 and PBS on RF 13 @ 7.1.
Your other strong stations are 8, 10 and 12 - these are Fox on 8 others are independent or real estate broadcasts.
14 is also FOX.
16 is Independent as is 34.
If it were me I 'd probably put up a full UHF/VHF antenna pointing about 307 degrees to get the Leavenworth stations.
This should also get you 8, 10 and 12 and you can add a UHF antenna of you want some of the independents around you.
I would go for one of these:
Winegard HD8200U - $120
AntennaCraft HD1850 - $150
Channel Master 3671 - $190
Price estimates do not include shipping.
And they probably will not fit your attic.
The HD Stacker is a VHF high (7-13) UHF antenna, so it would not work for channels 3 and 5.
