Your selection of equipment seems right to me. I'd be considering interference. Interference bothers VHF more than UHF. Potential sources of interference are power line noise and home electronics.
To check for power line noise tune your car radio to 530 AM and listen for loud buzzing as you drive within a block of your home.
To eliminate home electronics, turn off every circuit breaker in the hosue except for the TV set. Next unplug everything but the TV set and preamplifier. If VHF reception returns, start plugging things in and turning on breakers until you find the culprit.
