Thanks again for the input.
I took a tiny 24" flatsscreen with extension cords onto the roof climbed on top of my chimney and used a 6ft coax to each antenna holding by hand towards milwaukee and did an autoscan.
The small rca ANT705Z got
15.1
27.1,2,3
52.1,2,3,4,5
55.1,2,3,4,5,6
58.1,2,3,4
The rca ANT751 I thought would do better actually did worse with
52.1,3,4,5
55.1,2,3,4,5,6
58.1,2,3,4
Did an auto tune with ANT705Z laying on roof against stink pipe I'd mount my pole on facing Madison and got
15.1,2,3,4
21.1,2,3
27.1,2,3
52.1,2,3,4,5
57.1,2,3
Wonder if I should keep the small one I have that picked up the most and get the $20 amp listed above or return both and buy one of the others and attic mount it and hope for better reception.
If mounted outside I really like how small this one is. I couldn't see mounting a big clunky one that close to my overhead service.
I'm good at fabricating so clamps and pipe size shouldn't matter too much if I need to change something.

I was looking at this one previously and size wouldn't be too bad for mounting outside if it's better than the ANT705Z I tried.
I scanned the box with my phone and Walmart is the only thing that comes up and the picture isnt even close to what it actually looks like.
The box says
25x18x17"
174-216 Mhz VHF
470-698 MHZ UHF
if that helps at all
Wonder if I'd be even better off using two of these cheap 705's on same pole one facing milwaukee, one facing madison?
Its tiny, weighs less than a pound and only $39 each
I'm a little confused tho as why tv fool doesn't list many of the channels I received and the channel master site similar shows some of them but not all either.
Also wondering why I didn't get 3.1,2 or , 47.1,2,3. Whats different about these channels yet many other ones that show lower Nm db rating picked up just fine.
Edit- I just noticed 3 and 47 are 2* different from all the rest of the stations and something must be in the way or something. 21 still comes in at good so that kinda throws me off when the Nm db is lower on that station as well.
Any ideas?
