No. The acronyms stand for different, non-overlapping frequency ranges. Since
the #1 immutable requirement for radios to be able to talk to each other is that
they be on the same frequency, and since HF, UHF, and VHF radios are by definition
on different frequencies, that match would be harder to operate successfully than
a mixed marriage.

You have a choice of fiber, microwave, HF, UHF, VHF, carrier pigeons, etc.
What are the frequency ranges included in the following frequency subdivisions? MF, HF, VHF, UHF and SHF
Use LF or lower HF frequencies (rather than UHF or VHF), proper SWR tuning of antennas, radio amplification.
Very High Frequency and Ultra High Frequency. They are ranges of frequencies of radio waves in the electromagnetic spectrum. VHF ranges from about 30MHz to 300MHz, UHF is from about 300MHz to 3GHz. They are further subdivided into bands for; marine, amature, and other 2 way radio use, also designated channels for television and radio broadcast stations, as well as other uses throughout the world. In the US on the now defunkt analog television system VHF channels were 2-13 UHF channels were 14-83.
The so-called "2 meters" Amateur radio allocation is the band of 144 - 148 MHz in the US. Frequencies from 30 to 300 MHz are tagged 'VHF'. 'VF' typically means 'voice frequency' and is irrelevant to this discussion. "HF" = 3 to 30 MHz. "UHF" = 300 to 3000 MHz.
The OE-538 is a multi-function communications mast used on US and Australian submarines. The frequency range of the antenna covers typical military communications bands. VLF, HF, VHF, UHF (SATCOM and LOS) communications, L-band GPS navigation and Iridium SATCOM, and IFF.
No. The emission and absorption spectrum covers everything from UHF radio to X-rays. (There are no energy level transitions that correspond to the low energy HF or VHF radio bands and below. The lowest-energy transition is the one at 1420 MHz/21 cm.)
LF - Law Frequency (10 to 300 KHz)MF- Medium Frequency (300 to 3000 KHz)HF- High Frequency (3 to 30 MHz)VHF- Very High Frequency (30 to 300MHz)UHF - Ultra High Frequency (300 to 3000MHz)
Many ocean going vessels operate on HF bands and use satellite radios, none of which are accessible by most scanners. There are standard VHF frequencies/channels used by many boaters and ships though, and you can follow the link below for a complete list of them: http://www.navcen.uscg.gov/marcomms/vhf.htm
