7.4 Accessory Items
7.4.1 Antenna
Some applications for The Shark require The Shark to be installed into a metal enclosure
or an enclosure that would attenuate the RF signal. This makes transmission difficult and
can reduce the range significantly.
In this case, it is necessary to use an antenna/cable assembly to bring the signal out so
that line-of-sight with the other radio is possible, or to get the range back to an acceptable
distance.
Stevens recommends the following antenna for use with The Shark. Although other
antenna solutions may also work, this antenna accessory has been FCC listed for use with
The Shark. Please feel free to call Stevens to discuss antenna options and setup if
needed.
