I am planning an IQ Pro installation in an basement with no cellular reception and need to use an external/remote cellular antenna.
Does the IQ Pro (with the [Plastic/Metal] enclosure) support a wired external cellular antenna?
Are specific antenna models required?
According to Qolsys the IQ Pro with the plastic enclosure does not support external antennae, but the IQ Pro with metal enclosure does. (IQPR001M is the model number for the 319.5 and PowerG model)
The part number for the antennae are:
15 feet - LTE-15ANT
25 feet - LTE-25ANT
50 feet - LTE-50ANT
Here is a link to the manual showing external antenna installation.
