1. I would recommend a 4 ft spacing between antennas to prevent coupling
2. The Stellar Labs 33-2230 combiner specs show an insertion loss of 3.5 dB, while others such as the Pico Macom UVSJ specs show an insertion loss of only 0.5 dB and the Holland UVSJ as loss of 0.7 dB.
3. Did you need the preamp to receive your UHF stations?
4. Try just the UHF antenna with and without preamp and see what results you get
5. Try just the VHF antenna with and without preamp and see what results you get
The answers to points 3, 4 & 5 will help determine what is happening with your installation.

Thanks, Tim.
I didn't realize that the insertion loss is 3.5 db for that combiner. That's a lot. I ordered the Pico Macom UVSG and I'll install it as soon as it arrives. That should make a big difference I would guess.
I'll head up on the roof tomorrow to play with some of your other suggestions. Thank you again for your recommendations and suggestions.
