RF loss within Shure Cables

UHF/VHF

See the following document from Shure which shows the loss in their cables within the VHF/UHF range. Note that the following product lines operate in this range.

- BLX

- SLX-D

- QLX-D

- ULX-D

- Axient Digital

2.4Ghz

Cable loss at 2.4GHz, which is 2-3 times more than the loss per unit length at UHF frequencies (~500MHz). Attached is a chart that shows the relative loss of different cable types at VHF, UHF, and 2.4GHz frequencies.

All of the pre-made Shure cables for GLXD Advanced use RSMA connectors fitted to Times Microwave LMR cable, LMR-240 for the short ones and LMR-400 for the long ones. A second chart shows the losses for these Shure cables.

All 2.4GHZ cables are fitted with Reverse SMA, also known as RP-SMA (reverse Polarity) connectors. The coax cable is unrelated. The use of RSMA connectors is dictated by FCC restrictions on 2.4GHz devices that may be used by consumers in order to limit the likelihood of attaching commercial high-gain antennas.
