RG-58 (50 ohm) is about 0.195", quite lossy, suitable only for mobile installations (typically < 20 feet, < 150 watts). RG-6 (75 ohms) is about 0.332", typically used for cable/satellite TV.

Nov 28, 2019 · Has anyone ever tried running this with 300-ohm flat line and put the balun at the back of the scanner instead of at the antenna? If so did it make things any better or worse?

By using the chart above, you will see that with 100 watts at the antenna feedpoint, your effective radiated power would be 398 watts! Remember, you have to achieve about 6db gain or loss to to make much difference on the air to the other station on receive.

cable in the RG-58. This particular connector provides signals for radio antenna connections, electronics used for aviation, and for cond cting video signals. When the RG-58 cable combines with the BNC connector, it can produce composite video played on comm

Here's a quick line loss calculator to use Note that the simple program used for this web page gives a very close approximation for additional losses due to SWR.

Nov 8, 2024 · How does RG58 compare to LMR-100 & LMR-200 coax cables when it comes to shielding & signal Loss? Discover the most common characteristics & differences.

Feed lines also have a characteristic impedance value measured in ohms. Coaxial cable commonly used for Amateur Radio has an impedance of 50 ohms while ladder line impedances can vary from 300 to 600 ohms.

That is the only formula you need ever know to build a dipole antenna. This page uses the standard formula, 468 / f MHz to calculate dipole lengths. You may change this number if you know of a better number to use as your starting point.

This page covers RG-58/U,RG-59/U,RG-11/U,RG-214/U and twin lead coaxial cable types.The RG58, RG59, RG11, RG214 coaxial cable manufacturers are mentioned. The link to types and basics of coaxial line is also mentioned.

General Description: RG-58 type, 17 AWG solid .044" bare copper conductor, gas-injected foam HDPE insulation, Duofoil® (100% coverage) + tinned copper braid shield (95% coverage), polyethylene jacket.
