UHF RFID Antenna Cable, N Male to SMA Male, 10 m (LMR-400 Class, 50 Ω)
A 10 m, 50 Ω low-loss coaxial cable in the LMR-400 class with an N male connector for the antenna and an SMA male connector for the reader. It joins the N female panel, circular and traffic antennas to the SMA ports of Identium multi-port readers over the long runs a dock door, gantry or vehicle lane needs.

Overview
Joining an N female antenna to an SMA reader
Most of our panel and circular antennas, including the 865–868 MHz 9 dBi and 12 dBi circular antennas, have an N female socket, while the IHZ4 family of multi-port readers has SMA ports. This cable has the two matching plugs, so no adapter is needed at either end. It is also the class to use for any run around 10 m, because the thin classes lose too much over that distance.
Loss over a long run
LMR-400 class cable loses about 0.13 dB per metre at 866 MHz, typical for the class: about 1.3 dB over 10 m, where the same run in LMR-195 would lose about 3.6 dB. Since the loss applies to the reader's transmit power and again to the tag's reply, a thick cable is the cheapest range you can buy on a long run. The read-range calculator takes cable loss as an input, and the antenna guide explains how to lay out read zones.
Installing it outdoors
Fit the N connector to the antenna, then wrap the joint with self-amalgamating tape or a weatherproof boot and leave a drip loop so water runs away from the connector. Route the cable away from power conductors, avoid tight bends (LMR-400 class cable is stiff) and leave a service loop at the reader. Other lengths and a N male to N male version for antenna-side extensions are quoted on request: request a quote with your antenna and reader models. See all RFID accessories.

Frequently asked questions
Which of your antennas need the N male end?
The 865–868 MHz 9 dBi and 12 dBi circular antennas list an N female connector, as do most of the other panel antennas in the range; the Connector row on each antenna page says which. The 8 dBi and 9 dBi PCB directional antennas have cable tails ending in SMA female and take the SMA to SMA cables instead.
Is 10 m too long for a UHF reader?
Not in the LMR-400 class. The run costs about 1.3 dB at 866 MHz, typical for the class, which a reader running at up to 33 dBm absorbs without much effect on range. The same 10 m in a thin cable would cost about 3.6 dB. Keep the run as short as the layout allows all the same.
Do I need to weatherproof the SMA end too?
Only if the reader sits outdoors. Normally the SMA end is inside a cabinet or building with the reader, so only the N joint at the antenna is exposed and needs tape or a boot.
