WebFor singlemode fiber, the loss is about 0.5 dB per km for 1310 nm sources, 0.4 dB per km for 1550 nm. (1.0 dB/km for premises/0.5 dB/km at either wavelength for outside plant max per EIA/TIA 568 )This roughly translates into a loss of 0.1 dB per 600 (200m) feet for 1310 nm, 0.1 dB per 750 feet (250m) for 1300 nm. WebThe RG11 A/U is a single shielded and favourable coaxial cable for many applications with 75 Ω. This line is compliant with the UL-Standard MIL C 17. RG11 A/U: (Sheath colour: …

WebSo (with the assumption that VF = 1) if you have a piece of coax that is 7.5m long and you feed it with a 10 MHz sinewave, the delay (phase shift) will be 90 degrees. If it's 15m long then the delay will be 180 degrees. A 30m length will look like the same phase as the original sinewave expect it will be lagging by one full wavelength.

WebDec 7, 2024 · Caption: A TV with a wrong signal reception. If you’d like to calculate the loss of your aerial signal, there’s a simple formula: K1 x F + K2 x F + CLF x F = CL. K1 marks the resistive loss, and K2 is the dielectric constant. F stands for frequency in Hz, and the CLF is the connector loss factor. WebI am feeding it with rg-6 tv foam coax. I was thinking of using Rg-11 foam. This antenna is 140 ohms or so both on 14mhz and 18 mhz. The 75 ohm coax is 216 ft long, VF .82 guesstimated and is a perfect 1/4 multible for 17 and 20 meters. The feed Z xmitter end is 40-45 ohms j-0. The calculator says I would gain 1db or less by changing coax. WebA coax is a common transmission line construction and most rf cables are coax. The impedance of the coax is a relationship of the capacitance per unit length and the inductance per unit length. This tool will help you find the inductance for a given length of coax cable.
