The maximum GSM cable length should not exceed 10m, and should be
kept as short as possible. Longer runs will require the use of higher gain
antennae
The GSM antenna can be extended from its standard length with a Comb-
approved RF cable extensions. This will ensure proper RF impedance
matching and signal quality. Do not extend the GSM antenna by joining
cables with soldered
High Gain GSM antenna may be used to boost the signal strength.
The antenna must not be installed inside any metal box or mesh cage as
this will degrade the RF performance.
Always try to re-orientate or elevate the antenna if the signal strength is low.
Try reduce physical access to the antenna for the purposes of reducing
vandalism attempts. Mount the antenna inside the secured premises
