WiMo 70cm X-Quad Montageanleitung Seite 10

• When the X-Quads shall be used with fixed right hand circular polarisation both
planes are to be connected with a phasing harness. This harness is to be con-
nected directly to both antenna feedpoints and is made of different cables with
different lengths. There is only one feedline required. This solution is cheap,
but fixes the antenna to either RHCP or LHCP. It is not possible to use the an-
tenna with linear polarization. We provide plug-and-play phasing harnesses,
see the picture to the right.
• When the polarisation shall be switchable, our polarisation switchbox can
be used (only available for 2m). Two feedlines running down the mast are
required with exactly the same length. A short jumper is required between
switchbox and transceiver. The switching is done manually with the rotating
swi tch of the box.
• For remote-controlled switching we provide different switches for mast
mounting. Those switches come in waterproof boxes and are controlled
by a normal DC wire. The antenna connection is done with 2 short cables
and there is just a single feedline down to the shack.

Connecting our phasing harnesses.
The antenna must be assembled with the N-jacks facing down-
ward and backward like shown on the picture on the right. For
RHCP the longer cable of the phasing line has to be connected to
the horizontal N-jack. If connectors are confused the antenna
has LHCP instead of RHCP, and thus a loss of more than 10dB if
the opposite station uses RHCP!
Hint:
The black caps on the end of the connector box are only
needed in the moment the box is filled with seal. Should
they come out after years on the roof, the antenna's per-
formance is not affected at all.
