Notes
Some LMR Cables are available in 75 Ohm Impedance for up-links, etc.
Do NOT use RG58 if the RF feed line to the antenna is longer than 25ft., or if the actual attenuation of the cable is not known or unacceptable.
* The exact figures on all of these cables may vary by manufacturer. They are listed here as a reference only.
** Attenuation is in db/100 ft @ 2.4GHz
¹ Velocity of Propagation is the speed at which an electical signal passes through a cable.
