To have our engineers recommend the best system configuration for you, simply

email us at support@wireng.com with as many details as possible about the

structure where you need coverage, and we'll be pleased to assist you.

Installing Your System

The location of the Donor (external) antenna is critical because its path should

not encompass the service antenna(s), hence, the Donor antenna optimal
location will almost always be on a corner of the roof (or if the outside signal is

not too weak, on one of the outside walls). If installation on an external antenna
is difficult or undesired, you may use a directional window antenna such as the

WinAerial™, but only if there is a window in the structure that is in the direction
of the service provider(s) tower(s).

Once the Donor antenna has been installed, simply choose an indoor place for

the sohoBoost™ (near a power outlet), run the appropriate coaxial cable to it,
and connect it to the Donor Antenna port, either directly or through the

LightningPro™ for lightning strikes protection (highly recommended). DO NOT
POWER ON THE UNIT JUST YET.

The sohoBoost™ comes with the WideAnt-X™ as the Donor antenna, and the

DomeAnt-Alpha™ as the Coverage antenna. The two included ultra-low loss
coaxial cables lengths are 50 feet (for the Donor antenna) and 25 feet (for the

Coverage antenna).

As far as Service/Coverage antennas, it's always recommended to use at least
two of them, unless your space is quite small. In general, we recommend one

Coverage antenna for each 2,000 square feet of contiguous space. Simply keep
in mind that, the more Coverage antennas you have, the better the coverage.

Notice that you can connect up to eight Coverage antennas to one sohoBoost™
(via one EMSplit™ and two EMSplit4™), but you can keep adding more and

more Coverage antennas by inserting additional sohoBoost™ units with the
W2I™ inline converter option without limits on the size of the structure you

need to cover.

As far as the coaxial cables for both the Donor antenna and the Coverage
antenna(s), it is highly recommended that you use the WIR400™ Ultra-Low Loss

coaxial cable type (unless the distance between the antennas is very small, such
as 15 feet or so, in which case you may use the WIR195™ or WIR200™ low-loss

types).

Once the Coverage antenna(s) is/are installed, simply connect their cables to
the sohoBoost™ Coverage port (or to the EMSplit™ in case of multiple antennas)

and power on the unit. If the LIMIT red light is lit, you must change the
orientation of the antennas or increase the distance between them, as the unit

detected intersecting radiation patter between the Donor and Coverage
antennas. In such cases where the antennas' orientation cannot be changed

(i.e., when using omni directional antennas) or where the space is very small,
you must add one or more WBSA™ (Wide Band Signal Attenuator) to either or

both sohoBoost™ ports, to limit it's power and range.
