CK-868 Outdoor Circular Patch Antenna 868MHz 7dBi
This antenna covers the 868MHz band. The antenna has been
designed to be waterproof and is easy to install. It is
circularly polarised for reading in any orientation. It can be used
for improved indoor GSM coverage, due to circular
polarisation. VSWR is typically less then 1.2:1, giving a return
loss better then 20dB.

Mounting instructions using the optional mast bracket:
• Attach the L bracket to the antenna by means of the two No.10 x 13mm self tapping screws
provided. The figure below illustrates this for vertical polarisation.
• Attach the enclos ure to a mast (diameter 40-50mm) using the Econo-bracket assembly as
shown in below.
• The Econo-bracket can be mounted through different holes to achieve the desired tilt angle
of the antenna.
• For outside installation thoroughly seal connectors with self vulcanising tape to stop water
ingress.
