This adapter/pigtail assembly will provide you with a low-loss, pliable and mechanically safe connection between the MS-147 coaxial switch connectors found on your device and your external antenna cable. It is designed to work with antenna cables that have been terminated with an RP-SMA Male connector (our antennas use cables that are terminated with an RP-SMA-Male connector).
PLEASE NOTE: This pigtail adapter WILL NOT fit the CLEAR Atlas Stick USB modem. Please contact us for more info on the proper Y-Type adapter for the CLEAR Atlas Stick USB modem.
LMR-100 cable is more efficient (lower signal loss) than the RG-174 and RG-316 cables typically used by others...
When LMR-100 cable is used for the 2500MHz to 2700MHz WiMAX/TDD LTE frequencies used by CLEAR/Sprint Spark, it is more efficient than the typically used black colored RG-174 or the stiffer braided copper colored RG-316 cable used by other manufacturers (see LMR-100 vs RG-174 vs RG-316 cable specifications compared below).
So why do other manufacturers use RG-174 and RG-316 cable?
RG-174 is the typical standard cable used by most manufacturers as it provides a fairly efficient and mechanically pliable connection at a lower cost.
RG-316 cable provides for a lower attenuation (lower loss) of your signal when compared to that of RG-174 cable, however, it is a stiff cable that is not as pliable. It is also more expensive than RG-174 cable.
Most manufactures that use RG-174 would argue that at these short "Pigtail" lengths the advantage of RG-174 being more flexible/pliable outweighs the lower signal loss advantages of the stiffer, less pliable and more expensive RG-316 cable.
LMR-100 cable beats out both RG-174 and RG-316 cable! Albeit, LMR-100 cable is more expensive than either RG-316 or RG-174 cable...
However, LMR-100 cable is more efficient (lower signal less) than RG-174 and RG-316 cable. AND LMR-100 cable is much more flexible and pliable than the stiffer RG-316 cable used by others.
LMR-100 cable is therefore ultimately better suited for use as a "Pigtail" type of adapter as it is more efficient, will better absorb any transmitted physical shocks and stress imposed unto the MS-147 coaxial switch connector by the antenna cable and it is easier to use than the stiffer braided copper colored RG-316 cables used by others (however, I must admit that the coated braided copper RG-316 cable does look pretty cool and more techie).
See the technical/performance comparisons for all three cables when used at a frequency of 2600MHz below:
FYI: "Attenuation" is a measurement of signal loss. The lower the number the better.
