Installation Guide
Type N female, Crimp-On, Cable End Connector for .590 Coax P/N 7306-N-600
We will begin by installing the Type N female connector on a piece of LMR-600. This
process is the same for all the other types of cable with an outer jacket OD of 0.590.
These connectors fit on a wide range of coax types including, but not limited to: RG-
217/U, LMR-600, and other 0.59 inch OD coax.
Identify all connector parts (3 Parts):
Each connector consists of one body assembly (jack), one rear ferrule (crimp sleeve),
and one center pin (jack contact).
Coax Stripping:
First cut your cable to the desired length and then strip the black jacket back
approximately 0.83 inches. When the jacket is stripped cut the braid/foil back 0.23
inches from the fresh cut end. Finally, cut back the dielectric 0.16 inches from the fresh
end down to the center conductor. The braid needs to be cut back further than the
dielectric to insure that none of the braid or foil is touching the center conductor which
could cause a short.

Note: Do not nick the braid, dielectric, and center conductor if at all possible. Tinning of
the center conductor is not necessary if contact is to be crimped. For solder method, tin
the center conductor if the center is stranded. twist the center conductor very tightly
prior to tinning.
Install Method Selection:
Slide the outer ferrule onto the coax as shown below. Flare the braid slightly to allow
insertion of the connector main body. Important: Do not comb out braid.
Place the center contact on the center conductor of the coax so that it butts against the
cable dielectric. The center conductor should be visible through the solder / inspection
hole of the contact. Solder contact in place as follows:
Crimp-on the Ferrule
Use the 7505-HANDLE-600 crimp handle for the ferrule. (DO NOT CRIMP / CRUSH
THE CENTER PIN)

Solder the pin
Make sure the solder hole is facing up. Touch the soldering iron to the underside of the
center pin directly under the solder hole. Touch the solder to the center conductor
through the solder hole on the center pin. Allow the heat from the metal to melt the
solder so that it wicks into the center pin. Once the solder melts it only takes a tiny
amount of solder to make the connection. Do not allow the solder to pool over the solder
hole. The outside of the center pin should be free of obstructions for insertion. Do not
over heat the center pin which could cause swelling of the dielectric of the coax.
Main Body Install:
Install the cable assembly with the center pin already affixed, into the main body of the
connector. The knurled portion of the main body slides under the braid of the coax.
Push the cable assembly into the main body until the center pin snaps into place in the
dielectric of the connector.
Slide the ferrule (placed on the coax at the beginning of Step 2) over the braid and
completely up against the connector body. Using the 0.590 hex of the 7505-HANDLE-
600 crimp handle, crimp the ferrule at the location shown in the picture below (on the
ferrule, but right up against the main body of the connector).
Final Testing:
When this is completed, as a final test, you should always check resistance from the
center pin to the body with an ohmmeter in a low resistance scale. After verifying that
there are no braid –to –center pin shorts on the other end of the coaxial cable, you
should see infinite resistance (open).
