Almost all military transport and patrol aircraft use VHF.
If you are in a boat the frequency is 156.8 Mhz, also known as channel 16. For an aircraft emergency the VHF frequency is 243.0 Mhz.
Because a VHF broadcast theoretically could reach thousands of people ! Additionally, if it's (for example) a marine or aircraft emergency, there are specific emergency channels, which are monitored 24/7 by professional people.
Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.

You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.

Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.

history of vhf radio
I wouldn't think so. The uhf coupler is made NOT to pass vhf freqs. The transmitter and the coupler are made to operate in different bands.
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
Spending more on the miltary is called military industrial complex.
