    FWIU .... a "ohm meter (volt meter set to ohms) " can't measure antenna impedance because it does not transmit a set frequency for the antenna to resonate to . a antenna is not like a speaker or electronic component that has a fixed value .. it's impedance will change with the frequency it's radiating at . the multi-meter can tell you if it has a open or closed circuit .... but either can be perfectly fine depending on the design of the antenna and as long as the antenna isn't damaged .

    some base loaded mobile antennas will show as a closed circuit (DC grounded) antenna because thy use hairpin or capacitors in the tuning section ... the K40 is one but i don't know if the sirio is or not . with base antennas using a gamma to tune will show a open circuit , using a tapped loop (maco 58 for example) or tapped coil will show a closed circuit . the penetrator 500 hairpin will also show as a closed circuit .

    here's a short little article that discusses the difference some but not in a lot of detail because it's focus is on earth grounding

    you need a antenna analyzer to measure the impedance of the antenna .
