Greetings Studebaker839,
Lava HD8008 - ouch. This is one of those designs as ADTech mentions that aren't ideal. Anytime you see a manufacturer boasting about mileage and the built in amplifier with this space age design - RUN. Translation here is that the antenna's design has no real gain and they are cheating by amplifying the signal at the antenna itself and saying it has this tremendous gain and reception capability - which it doesn't. Unscrupulous advertising to say the last. Real gain is achieved through elements that capture the signal out of the air. This is why you used to see large 15' long aerials. Those antennas created real gain via their size and elements. This is why the DB8e is large with its 4 panels. It utilizes real gain.
If I was at your location, I'd scrap the Lava HD8008 and start fresh on your roof. If you see OKC signals at magnetic 153, that's a good sign. It shows a proper antenna may do well for you.
A DB8e mounted on your roof free of obstructions orientated to magnetic 153 ought to do the trick for UHF signals. A second VHF only antenna will likely be needed for high-VHF reception in KOCO and KETA. The Antennacraft Y10713 would be called on for those signals. Y10713 orientated to magnetic 153 as well. Combine signals with an Antennas Direct EU385CF signal combiner. Run single coax into home.
There are plenty of roof options to mount. Whether it be tripod or roof mount. A critical criteria though is making sure in the direction of magnetic 153 no blocking structures or foliage is in the immediate vicinity.
Cheers.
