The Facts About Radio Communication Distance

-

What’s the range for a radio to communicate with someone? How many miles? This is almost the most common question people ask before getting a new two-way radio. But if you check the answers for the same radio, you may find many disappointed people saying that only 0.5 mile, but also some saying 3 miles, 5 miles, and so on. Why they're so different? Because the type of terrain and equipment can greatly affect the talking range. You often see ads for two-way radios saying "up to 36 miles" or more. Here the keyword in the advertisement are "up to". This maximum range is more theoretical than realistic. So how far can you really expect to talk? The key considerations that affect range are: signal type, antenna, obstructions, and signal strength (wattage). No single factor is a silver-bullet to extend your communication range. But taken in combination, they can mean the difference between getting 1/2 mile range, vs 6 miles or more. This article from Baofeng discusses...

EMP is a low-probability threat, but one with potentially high consequences should it occur. Dr. Arthur Bradley, a recognized expert in EMPs, their effects and how to protect against them, has a video where he offers suggestions on how to protect against an EMP. https://www.youtube.com/watch?v=JNBj3nkVqEQ Dr. Bradley's recommendations are based on his research and would seem to offer a reasonable degree of protection against EMP... unlike some suggestions we see in "prepper" groups suggesting such things as using a microwave oven as a Faraday cage. There is a common misconception that a microwave oven is a Faraday cage. It is not. Not even a close approximation. Go in your kitchen and open the door of your microwave. Look at the mating surfaces between the door and oven. There is no bare conductive metal at all, usually power coated sheet metal or plastic on both surfaces. It is essentially *wide open* from an RF perspective except right at 2.4GHz. Attenuation at 2.4GHz...
