They should also be able to visit the boat and test the antenna using an in-line SWR (standing wave ratio) meter - VHF type, not CB radio - which measures the ratio of forward and reflected power. "Keying" the hand mic, as it's known in radio circles, activates the radio's internal transmitter. The ohms reading should be zero. How do I test a VHF antenna with a multimeter? Step 1 Connect one of the leads on the ohmmeter or multimeter (the multimeter can act as an ohmmeter) to the antenna mast on the vehicle. Some TIPS on measuring VSWR and troubleshooting M2 Antennas and other commercially available HF antennas. If the resistance is greater than that, the antenna or cable is damaged, which is preventing a signal from reaching the reception device. Hook up a dummy load to the antenna connection on the meter. There must be little to no resistance because the circuit must be continuous throughout the antenna. I have a closed circuit when the antenna is connected to . Check the cables properly to ensure there’s no wear or breakage to the casing. 1 x PL259 plug. ART-3 tests receiver function as well as output power and VSWR (antenna efficiency) Frequency Range: 155-158 MHz. An antenna receives a radio signal and then generates an electric impulse that is transferred to the conductive wires to the television. Touch one lead of the multimeter to the metal part of the antenna and touch the other lead to the metal core of the cable. For center-loaded and magnetic types, that will be a stainless-steel whip.
