How far are the antennas spread apart from each other, the 9 x 8 1/2" has some VHF reception ability especially on CH 12 & 13 there may be some interaction going on with the VHF antenna you have up there.
A properly built 9 x 8 1/2 with a 30" wide reflector (could be just some strips of metal) pointed ENE could get the VHF and UHF stations from that direction so maybe no need for the seperate VHF antenna.
So far I have been testing the 9 x 8 1/2 on ground level inside my living room.
I can get a signal inside my house from 31.1 WTIC Hartford that actually does come in strong enough to watch the channel and make changes to the antenna.
I took the reflector off of one of the 7" 4 bays, and added it to the 9 x 8 1/2, but decided it was too flimsy when I added more cardboard and foil to the current size so it was wider than the spread of the 9 x 8 1/2" whiskers , so I am going to devise something different.
I have added that reflector back to the 7" as you can see its size in the images I will put in my next reply.
Buying a roll of 1 x 1 1/2" wire fencing for a 40 x 40" reflector is not in my interest at this point.
I wish there was a decent way of tying two UHF antennas together which are pointed in different directions.
Not sure how those 8 bays are connected with a splitter and no signal degrading is mentioned. I tried that near the antennas, but again some signals suffered a 30% loss in doing that.
As for a rotor, keeping the antenna clear of those vertical roof support 2 x 4's and far enough away from the slanted attic ceiling presents a minor problem with 360 degree rotation if a reflector is used.
As shown in my VHF picture above, there are 2 x 4's running on 45 degree angles all across the attic, which would also hinder rotation if the antenna was lowered enough to give decent antenna clearance and distance from the slopped attic ceiling.
When I put my first 7" 4 bay up, like in the picture above, the antenna was high above and the next area over from the VHF antenna, theey were basically 3 feet apart, one higher then the other, it is out of view in that picture I posted above, but as you can see at the splitter, another RG6 coax runs up, the UHF used to be there where it was very close to the ceiling, roughly 3".
It was also built on one of the permanent vertical 2 x 4's at that point and was in a fixed position at N-N-E.
I removed it and built it on a .50 x 2 1/2" board, added the reflector and hung it from the peak with a wire hanger.
The reflector is being held on by two pieces of .50 x 2 1/2" boards, each is 5 1/2 inches long.
The top board has a hole in the center where the wire hanger goes through and that wire hanger is screwed into the peak of the pitched attic ceiling, so the antenna is suspended in mid air and is a minimum of 2 feet clear of the angeled ceiling.
To my understanding, for an antenna to perform correctly, it can not have anything close to its focal point, it needs a few feet clearance from other objects, including wood and roof shingles.
I have that antenna down in my living room right now, I am going to bring both antennas out in the yard and take pictures of them both and post them in my next reply.
One will be the 7" 4 bay with reflector, the other will be the 9 x 8 1/2 4 bay presently without a reflector, as I have to make something more solid and more stable.
By the way, just so you all know, I rent, I do not own, so this is why I can NOT erect an outdoor antenna, otherwise I would have a 60 foot tower with a rotor and a VHF/UHF combined antenna on top of it.
The attic is a private area inside my rented space.
