2.4 TX Antenna
Tx antenna will be installed indoors. In normal configurations, antenna is to be attached to the
ceiling structures. Proper installation procedures must be followed as defined in site specific
construction drawing. As a general rule the TX antenna shall be kept a minimum distance of 6
feet from any metallic vertical structures on other types of obstructions.
This radio transmitter (FCC ID: A4P-100-0013-01) has been approved by FCC to operate with the
antenna types listed below with the maximum permissible gain and required antenna
impedance for each antenna type indicated. Antenna types not included in this list, having a gain
greater than the maximum gain indicated for that type, are strictly prohibited for use with this
device.
This radio transmitter may only operate using a vertically polarized antenna.
2.5 GPS Receive Antenna
GPS antenna should be installed such that it has clear view of sky. Ideally, you would keep the
antenna close to the ground away from obstruction
• Keep any horizontal blockage smaller than 10 degrees
• Obstruction Clearance guideline
– If it is 1 ft wide it should be at least 6 ft away
– If it is 10 ft wide, it should be at least 60 ft. away.
– If it is significantly less than 1 ft wide (like a guy wire, or a post) it should not cause any
measurable effect
