We often get the question, when is it suitable to use a stock OEM antenna that is supplied with the radio? We look at a live demonstration of the stock OEM antennas that are supplied by TYT with the MD-UV390 DMR dual band radios to see at which frequencies they remain below the threshold SWR of 3. We then go on to have a look at some other antennas that are supplied with common handheld's.
