Preventive Maintenance
Like all our products, the CHA P-LOOP 3.0 is built to be rugged, long lasting and with details in mind. The
craftsmanship of the system is unique to Chameleon Antenna
TM
. The materials used in this antenna are
water and rust resistant and do not require preventive maintenance, but they should be inspected for
damage and cleaned with mild household cleaners after field use.
