antenna, you will need a “N” connector. On the Eggfinder side, you will need a RP-SMA
FEMALE connector on the cable (INSIDE threads with a JACK in the center). We
recommend that you use the shortest cable that you can practically use, if you mount the
receiver just behind the rear of the antenna you can generally keep this cable to under 6”. Be
sure to get a cable that’s rated for the 900 MHz band; WiFi cables work fine, since WiFi runs
at 2400 MHz, so the loss will actually be less than the cable’s specifications. Some cable types
that are commonly used for these frequencies are LMR-400 and RG-174; if you have a local
electronics store nearby, you can usually get them for under $1 per foot.
We generally recommend that you purchase a pre-made cable for connecting to an external
antenna, coaxial cables are a pain to work with if you don’t have the tools and don’t do it all
the time, and a commercially made cable is generally going to have lower loss than a
homemade cable. Look around on the Internet, you should be able to find a 500mm RP-SMA-
to-N cable for well under $20.
