Emergency Portable Antenna for 2 Meters

In times of emergencies the difference between communicating, and not communicating, can come down to the antenna. Now let's be honest, the antenna that is typically sold with most amateur handy talkies is far from an effective radiator. One of the first things most amateurs do when purchasing a new radio is to replace the antenna with an upgraded antenna from a number of manufacturers that specialize in antenna construction.

But even with these fancy upgraded antennas some area will continue to have difficulty communication due to surrounding terrain. Often the solution is to get the antenna outside, and higher, but most people envision a large antenna atop a steel mast, not so.

Communication plans built around disaster communications need to be highly portable, inexpensive, and effective. For ages many hams have been constructing effective two-meter antennas out of simple ladder line. This antenna is easy to construct, can be stored in a shoe box, and is easy to deploy in times of emergency. This antenna will help squeak out all the effective power out of that handie talkie.

The parts can be located at many local ham radio specialty stores and electronic supply stores. Keep in mind that you will need an adapter to connect the feedline to the radio. You might want to take your radio with you so they can select the appropriate adapter.

Remember, test the antenna before you need it in an emergency. Try it in different locations around the homestead to see where it's most effective.

Now while this might be an easy construction for some, others might be uncomfortable with antenna construction. If you have questions seek out assistance as an improperly constructed antenna can damage your radio. It's best to seek out assistance when needed.
