Along with the cable, a proper connector must be chosen. The I/O module uses an RPSMA Male (plug) connector. The
optional high gain antenna has an N type Female connector. Therefore, an antenna cable that has a RPSMA Female jack at
the module end and a N type Male connector at the antenna end the must be chosen.
If the supplied antenna needs to be extended, a cable with an RPSMA Female jack at the module end and an RPSMA Male
(plug) at the antenna end must be selected since the supplied antenna has an RPSMA female (jack).
Antenna Cable Part Numbers
Following standard cables available for purchase. The cable part numbering format is as follows:.
TTTT-AABB-LLLL
Where,
TTTT = Cable Type (400M = LMR400, 195M = LMR195, 100M = LMR195)
AA = Connector A (NM = N-Male, SL = RPSMA Male (Plug)
BB = Connector B (NM = N-Male, SL = RPSMA Male (Plug)
LLLL = Length in inches (ex: 6 = six inches, leading zeros are not necessary)
For example, an 400M-NMSL-24 is an LMR400 cable with a N Male on one end and a RPSMA plug on the other, 24 inches in
length.

Lightning Arrestors
A lightning arrestor can prevent damage to the radio due to high energy transients during lightning strikes. The arrestors limit
surges to less than 45 volts in approximately 100 nanoseconds. A gas discharge tube changes from an open circuit to a short
circuit in the presence of energy and voltage surges giving those surges a direct path to ground, thus protecting equipment.
They are designed with a rugged housing and high quality plated brass "N" connectors. It also features a user replaceable gas
discharge tube (LA350GT) and are available in three models: the LABH350NN and the LABH2400N both allow bulkhead
mounting and connector pass-through and the LAIL350NN allows inline placement only.
