Of course, no one can guarantee what the FCC might do in the next few years, but so far they have no plans to change the 30-50 MHz band like they have with everything else. That's why I think it will be around unchanged for the smart people who get licensed there in the next few years. Because of this, you can expect better coverage using less expensive antennas and radios than others using more expensive equipment. I could write a book on all the technical details, but what you need to know is that there is a golden opportunity to acquire a good radio system that should work well for another 20-30 years if needed without replacing anything except for occasional minor repairs. However, you might be suprised to find out that many 30-50MHz frequencies that were in use years ago have now been abandoned by the big power companies and others.
Most areas have hundreds of unused channels that can be applied for with little effort.
I recently acquired two 48 MHz power frequencies that were not being used anywhere in my state. Good used equipment in the low band is available in large quantity and is very reasonably priced becase of the move to 800MHz by large power companies and others. We have bought thousands of these units in the past for years, because we see a comeback to the basics that works better for more people. Before you buy a new system of any kind you might want to consider all the pros and cons before jumping into a monthly service agreement that promises to get only more expensive each year. Most new systems will be obsolete and will probably shut down within five years due to new technology.
