frequency range from 1050 MHz to 1700 MHz and passes a 10 MHz reference signal to the BUC. This protocol and the
cabling is dependent on the specific modem and BUC used for each solution. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
3.3 RXcable
This N-type IF cable sends the L-Band (950 MHz to 2150 MHz) signal from the antenna to the modem and provides DC
power for the LNB. It connects the antenna RX OUT port to the modem primary RX IN port (Rx 1). The RX cable works in
the frequency range from 950 MHz to 2150 MHz and provides power for the LNB. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
3.4 LNB-to-antenna cable
This cable connects the LNB to the antenna RX IN port. By default Kymeta provides a 0.3 m (12.0 in.) LMR-195 cable,
with a right-angle N-type connector. The connector is hex and knurl at each end. This cable comes attached to the ODU

6 Clean the u7 antenna
Prior to cleaning any part of the u7 antenna, ensure it is powered off.
General cleaning
Blow or rinse off loose debris first, and then apply a cleaning agent and use a clean, soft towel to clean the stained area.
Avoid scrubbing and do not use abrasive materials when cleaning the terminal components.
Avoid exposing rubber parts (for example, gaskets) to alcohol or alcohol-based cleaners, for they can deteriorate the
integrity of the rubber part.
General cleaning agents
Clean finger prints, smudges, salt spray, and light marks with isopropyl alcohol products: CAS Number 67-63-0. It is safe
to use isopropyl alcohol on the assembly.
Clean difficult stains, such as oil, grease, soot, ink, and other soils with LPS Precision Clean Multi-Purpose Cleaner
Degreaser at 10 to 1 dilution.
Connectors
Use a soft bristle acid brush or cotton swab with isopropyl or denatured alcohol to gently clean all connectors. Take extra
care when cleaning RF air-dielectric connectors and don’t damage, bend, knick, push in, or pull out the center connector
as this will change your signal. Carefully clean any surface corrosion on the exterior of the connector. Do not scrape or
over scrub the connector as this will damage the connector coating and render it more susceptible to corrosion.
Ensure connectors are completely dry before reconnecting.
Screws
Use a soft bristle brush and isopropyl or denatured alcohol to clean lightly oxidized screws. Replace heavily corroded or
oxidized screws when possible. For information on replacing parts and components, see section 9 Component
replacement.
