The 10 Meter Band consists of frequencies stretching from 28.000 to 29.700 MHz . This means that you can still use a standard CB antenna- just be sure to get an antenna that has a power rating that will handle the power output of your 10 meter radio.

So realistically, for two people carrying a handheld two-way radio, the maximum communication distance on flat ground with no obstructions is around 4 to 6 miles . So you may be wondering why you see radios that have range claims of 25 miles or higher. Technically they could communicate that far.13 Ağu 2020

Ham radio operators use the 2-meter band for general conversations as well as for emergency communications . Ham radio operators are often the first called upon to assist in major disasters with communications between the public and emergency services such a law enforcement, fire and emergency medical services.

For this reason, a microwave radio repeater with transmitter and receiver dishes mounted on 30-metre (100-foot) towers has a maximum range of approximately 50 km (30 miles) , whereas the maximum range will increase to approximately 80 km (50 miles) if the towers are raised to 90 metres (300 feet).
