WebAt VHF/UHF frequencies, the feedline loss can result in significantly less power applied to the antenna compared to the transmitter power. For example, transmitting 100W into 80 feet of RG-8X coax to an antenna with an SWR of 1.4:1 at 146.52 MHz will result in only 46W of actual power at the antenna. Here is an excellent coax loss calculator. WebDec 4, 2024 · The recommendation defines a difference of one S-unit corresponds to a difference of 6 dB, equivalent to a voltage ratio of two, or a power ratio of four. Signals stronger than S9 are given with an additional dB rating, thus “S9 + 20 dB”, or, verbally, “20 decibel over S9”, or simply “20 over 9” or even the simpler “20 over.”.
