WebJan 24, 2024 · 50 ohms UHF-UHF antenna Coated with Nickel plate On top of our list is the Steren 205-700. This coax is fully coated and has connectors made with a nickel plate. One of its centers of attraction is the well-versed jumpers, actively working with antenna tuners, main antennas, and switched meters. WebIt means that if you apply 1 V RMS sine wave of that frequency at the end of the antenna, a 1/50 A RMS current will flow in the antenna at that point. V = IR. Exactly. This can be generalized to the statement that the ratio of RMS voltage to current at any point on the antenna is 50, and the unit is, of course, ohms.
