2. RG-58 - Wikipedia

   en.wikipedia.org/wiki/RG-58

   Plain RG-58 cable has a solid center conductor. The RG-58A/U features a flexible 7- or 19-strand center conductor. Most two-way radio communication systems, such as marine, CB radio, amateur, police, fire, WLAN antennas etc., are designed to work with a 50 Ω cable. RG-58 cable is often used as a generic carrier of signals in laboratories ...

3. G5RV antenna - Wikipedia

   en.wikipedia.org/wiki/G5RV_antenna

   With no matching unit, Varney specified 75 Ω cable be used at the junction of the ladder line and coax (not 50 Ω); the higher 75 Ω impedance makes a closer match the end of the ladder line. An earth-grounded 4:1 voltage balun may be used to connect the coax to the ladder line, and 1:1 current balun should be used between the coax and the ...

4. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   The 50 / 52 ohm cables are widely used for industrial and commercial two-way radio frequency applications (including radio, and telecommunications), although 75 ohms is commonly used for broadcast television and radio. Coaxial cable is often used to carry signals from an antenna to a receiver.

5. Antenna feed - Wikipedia

   en.wikipedia.org/wiki/Antenna_feed

   Most transmitters have a standard output impedance of 50 ohms, designed to feed 50 ohm coaxial cable. The transmitter is matched to the feedline by a device called an antenna tuner, antenna tuning unit, or matching network, which may be a circuit in the transmitter, or a separate piece of equipment connected between the transmitter and feedline.

6. List of RF connector types - Wikipedia

   A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141-inch. 4.1-9.5 connector, standardized as DIN 47231 (in 1974) and IEC 60169-11 (in 1977) 4.3-10 connector, formerly known as DIN 4.3/10, now standardized as ...

7. Coaxial antenna - Wikipedia

   en.wikipedia.org/wiki/Coaxial_antenna

   In the most basic form, a quarter-wavelength section of coaxial cable is prepared such that the inner and outer conductors are separate but still attached to the remaining cable. The outer (shield) conductor is connected to a quarter-wavelength conducting sleeve into which the cable is inserted, and the inner conductor protrudes vertically ...
