Chapter 14 ‒ RF Range and Selectivity
Using the proper antenna type and placement can dramatically impact the usable range of any wireless microphone
system. For an overview of general antenna selection and placement, see the “Antenna Setup” (http://www.shure.com/idc/
groups/public/documents/webcontent/us_pro_antenna_setup_ea.pdf) educational publication on www.shure.com.
The following antennas are compatible with the Axient Wireless System.

system. Better quality RF cables have lower loss per foot; examples are RG8/X and RG213/U as indicated in the table
below.
Type of Cable Loss @ 400 MHz (100 ft.) Loss @ 800 MHz (100 ft.)
RG58A/U (Belden 8240) 8.4 dB 12.7 dB
RG58C/U (Belden 8262) 11.5 dB 18.5 dB
RG8X (Belden 9258) 6.6 dB 9.9 dB
RG8/U (Belden 8214) 3.9 dB 6.1 dB
RG213/U (Belden 8267) 4.1 dB 7.1 dB
Premium RG213 (Belden 9913) 2.6 dB 3.9 dB
