Most radios sold are VHF. But for those who need UHF, The dual band radios are less cost than a VHF & UHF radio. While the companies used to sell both, sales figures show UHF stand alone radios don't sell well. There are many low populated areas where there are only VHF repeaters exist. Years ago Yaesu had a FT 2400 VHF radio, & it sold for $300. That was the going rate for a VHF radio. But they also offered a 7400 in Japan. People here found out & asked for it, but it took 2 years until it was sold here. It was a fabulous radio, but sold for $479 & $50 for the PL decode board. That was almost dual band price. It didn't sell well, but I still have mine. Years later I got a new one on close out for $200. They are fabulous radios, but not cost effective.
