Spelling: RG-213
RG-213 [1] is a replacement for RG-8 [2]. RG-8 [3] was the popular
choice in RG [4] CoaxialCable [5] for years. Unfortunately, RG-8 [6]
quality is unreliable. RG-213 [7] is similar to RG-8 [8] but is built
to Military standards. The improved quality performance is well worth
the higher cost. RG-213 [9] has a 95% shield coverage.
Good quality RG-213 [10] attenuates a 2.4 GHz signal at around 0.5
dB/meter. Because of this, it is not recommended to use RG-213 [11]
spans greater than 7.5 meters (~3.5 dB attenuation) for 2.4 GHz
applications, otherwise the loss is too great for a reliable signal.
If you need a length of cable around this length, or greater than this
length, you should definately consider using LMR-400 [12] for the job
instead.
RG-213 [13] was designed more for signals in the range of 200 MHz to
600 MHz, and one common application is for STL [14] use by FM radio
stations.
