HF, VHF, UHF, SHF, WTF?

UHF, VHF, all the HF’s! What do they mean??!

Well, its simple really. HF stands for “High Frequency.” This is generally reguarded to be around 3Mhz to 30Mhz.

VHF stands for “Very High Frequency” which is where most of the repeaters in southwest Missouri lay. This ranges from 30Mhz to 300Mhz. This is also where you’ll find a lot of business radios, public safety, FM Broadcast stations, and of course, amateur radio.

UHF stands for “Ultra High Frequency.” This is between 300Mhz and 3Ghz. There are MANY services in this range including businesses, public safely, amateur radio, computer WiFi, cell phones, TV stations, FRS/GMRS blister pack radios, cordless phones and MUCH more.

SHF is “Super High Frequency.” This is between 3Ghz and 30Ghz. Although there isn’t as much “action” up there for day to day use as there is in VHF and UHF, there are still many important services that use this range. The most popular consumer use is for 5Ghz WiFi on your new smart phones and computers.

As you can see, the naming of these ranges is not the most sophisticated, but the uses sure can be!
