Specs Summary
LMR100 Times Cable
LMR-100A is a Times Microwave 50-ohm flexible coaxial cable with a 0.100" outer diameter, delivering significantly lower signal loss than RG-174 or RG-178 at the same form factor. Its foil-plus-braid shield offers 40 dB shielding effectiveness. A popular upgrade for short antenna pigtails and module connections in WiFi, cellular, and GPS applications.
RP-SMA Connector
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
UHF Connector
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Common Applications
This RP-SMA and UHF cable assembly is well suited for short antenna pigtails, module-to-antenna connections, and compact RF assemblies. The combination of reliable RP-SMA and UHF connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.

Frequently Asked Questions
What is LMR100 Times coaxial cable used for?
LMR-100A is a Times Microwave 50-ohm flexible coaxial cable with a 0.100" outer diameter, delivering significantly lower signal loss than RG-174 or RG-178 at the same form factor. Its foil-plus-braid shield offers 40 dB shielding effectiveness. A popular upgrade for short antenna pigtails and module connections in WiFi, cellular, and GPS applications.
What is the signal loss of LMR100 Times?
At 1800 MHz, LMR100 Times has approximately 23.8 dB of loss per 100 ft (0.238 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 300 MHz, limited by the lowest-rated component across the cable and connectors.
What is a RP-SMA connector?
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
