Answer: No. The 1/2 wave antenna (also called a dipole antenna) is built of two 1/4 wave elements that interact with one another to launch the electro-magnetic wave. It does not require a ground plane to work efficiently.Aug 23, 2017');})();(function(){window.jsl.dh('7','');})();(function(){window.jsl.dh('_jjieYMeeFpe_0PEPqIOEqAE33','

In an instructable, the formula for calculating antenna length was given as "length in meters =300 / frequency in MHz". The example given was for a Bluetooth antenna with a frequency of 2450MHz. The antenna length was calculated as 300/2450 = 0.1225m = 12cm.Mar 29, 2010

80.7 inches is approximately 2 meters, which accounts for calling the band a "2 meter band." A true dipole has each of the two radiators (the wires in this case) one quarter wave length long.
