The purpose of coupling antennas in a array is to achieve either gain or
to create a special shape of the radiation diagram.
The branches of the cable harness are impedance transforming sections
and must not be shortened.
The cable harnesses are fully waterproof and protected against
hostile environments.
By using these cable matching harnesses, two/four antennas can be
combined together and fed in phase keeping a low SWR and
minimum insertion loss.
The antennas are supplied complete with clamps for mounting on
30 - 58 mm / 1.18 - 2.29 in. diameter mast tube.
