About RG58
Electrical characteristics of RG58 The typical impedance is within a 2 Ohm range of 50 Ohm. It operates at frequencies up to 5GHz. The conductor resistance is 38.4 Ohm. The dielectric resistance is 500 Ohm.
Structure and material composition of RG58 cable
Like all other coaxial cable, RG58 comprises an inner conducting wire, surrounded by and insulating layer and outer conducting shielding. RG58 coax cable is typically manufactured to the U.S. specifications MIL-C-17F and MIL-C-17G 9.
RG58 is a coaxial cable type for antenna cables, made to strict U.S government specifications. The ‘RG’ pre-fix stands for ‘Radio Frequency Government’ and the number refers to the gauge of the cable.
RG58 applications This coax cable performs well for a variety of radio frequency communication applications in a low-power setting. Key applications include:

Maximum Input Power is defined as: The maximum amount of power (voltage given in Watts) that is able to be transmitted to a single antenna without damage to the antenna port from overloading.Maximum Input Power is a key parameter commonly seen on antenna specifications and datasheets. It may be termed ‘power handling’ or designated as [...]
1.13mm coaxial cable is the most commonly-used coax for U.FL cables - especially short cables. 1.13 is the only coax that can be used with MHF4 cables. When connecting U.FL connector to a jack on a miniPCI card or board, sometimes the tight space requires the use of 1.13mm cable, because it is very thin and [...]
LMR-200 "Low loss cable" differs from RG58 and other coax standards by double shielding and less attenuation (signal loss in the cable) than the standard cables (e.g. RG58). LMR-200 is equivalent or better quality compared to LMR-200 (generally better because LMR-200 is double-shielded).Rated for outdoor use and are also suitable for indoor use. very flexible/easily bendable coaxThe [...]
Interference and Cable Shielding Shielding protects against both leakage and absorption of stray radiation of electrical noise by cables.Electrical "signal noise" interferes with the operation of antennas and antenna cables. Cables carrying high frequency charge naturally pose the risk of EMI transfer - both from shedding interference as well as accepting it. While insulation protects antenna cables from physical [...]
LMR-100 is a low loss, double-shielded coaxial cable type that is Data Alliance's standard for short versions of antenna cables with all of the following connector types: RP-SMA, SMA, N-type connector, RP-TNC, MMCX, 50 Ohm BNC connectors, and FME. LMR 100's range of frequency band compatibility (from 0 to 18GHz) and 50 Ohms impedance matching, makes it suitable and compliant for all the following applications:All WiFi [...]
Beamwidth is the angle from which the majority of the antenna’s power, as illustrated on the radiation pattern's main lobe, radiates. It may be measured in the horizontal or vertical planes and is the distance between two points where the power is less than half of the maximum.Beamwidth varies with the physical and electronic characteristics of [...]
Polarity is a key electrical characteristic to be considered when selecting an antenna. Like-matched antennas in an RF set-up will have optimal power or signal transfer in point-to-point applications. Polarity is as important as gain, radiation pattern and VSWR. In transmitting antennas, the polarization of an antenna is the direction of the electromagnetic fields produced by the antenna as energy radiates [...]
FPV (First Person View), are remotely controlled vehicles from a pilot’s or drivers point of view. They include unmanned aerial vehicles such as drones and ground vehicles such as RC cars and land moving equipment. FPV video feed and control signals are transmitted across various frequency bands depending on desired range and application. Most FPV [...]
