Heavy Duty RP-SMA magnet base + 11 ft. CFD-200 extension cable for RAK 2 Miner or Nebra Indoor


Pickup available at 2251 NW 41st Street

Usually ready in 1 hour

Our heavy-duty magnet base with RP-SMA connector features 11 feet of high-grade CFD-200 RP-SMA male-to-female extension cable built into the base. This means you can extend your RP-SMA antenna with very limited loss.

This is a great option for short-range extension of your RAK 2, SenseCAP, or Nebra Indoor miner. This does not work with the Bobcat antenna. Simply connect the factory antenna to the RP-SMA connector on the base, and the RP-SMA connector on the cable will connect to your miner. The base is magnetic so do not put the base right near a computer hard drive. 

Cheap entry-level magnet docking bases for antennas typically have cables without shielding, giving you as much as 6 dB of gain-loss over the same length cable. Our thick shielded CFD-200 cable limits gain loss to just 1 dBi for 915 MHz (1.8 dB for 2.4 GHz WiFi), helping you preserve your antenna gain.

Heavy Duty/Heavy Weight
When you need your magnet base to stay upright in higher winds, lower-cost lightweight alternatives can't form a strong bond to the magnetic surface and are likely to fall over. Some bases may tip just due to the weight of your antenna. Our heavy-duty magnet gives the total base a weight of 11 ounces, compared to just 3 ounces for an entry-level base.

Compatibility: This base has an RP-SMA female connector on the top and an RP-SMA male connector at the end of the 11-foot cable. RP-SMA is reverse polarity SMA, so the female port has a pin and the male has a hole, as the gender with RP goes by threading. This base is compatible with many popular RP-SMA antennas, including all of the RP-SMA antennas we sell from ALFA Network, Inc. on our site.

We do recommend RokTape to seal all outdoor connection points.

Bulk/High Value Order Returns

For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.

Nice Add On

Using this for just a couple of days. I have got a noticable improvement over the other antenna I was using
