HN series connectors have a 50-ohm impedance and threaded coupling connectors designed for
high-voltage applications. These connectors are weatherproof. The frequency range is 0-4 gigahertz. The
HN series is used with medium size coaxial cable such as RG-8/U, RG-9/U, RG-87/U, RG-213/U, RG-
214/U, and RG-225/U. Figure 1-27 shows three typical HN connectors. Figure 1-28 shows how HN
connectors are attached to coaxial cable. Table 1-15 indicates which HN connector to use with what
coaxial cable type.
N series connectors are low-voltage, 50-ohm, threaded coupling connectors designed for use with
small and medium size rf cable. They have a 1,000 volts peak rating and are weatherproof. There is a
group of N series connectors that are 70 ohms and are numbered UG-98A/U and UG-96A/U. These 70-
ohm N connectors are designed for cables such as RG-61C, RG-11/U, and RG-13/U. The 70-ohm
connectors will not mate with 50-ohm connectors of this series. Figure 1-29 shows three typical N series
connectors. Figure 1-30 illustrates the method used to attach N connectors to coaxial cable. Table 1-16
shows which N connector to use with what rf cable type.
