How to Optimize the TX300-V
Antenna
Introduction
The Goal of this memo is to present ideas how to
better optimize the use of the TX300-V. It will
document certain procedures that help users of the
TX300-V set the system up properly.
Antenna Installation
Antenna Installation
A. Selecting an Antenna Location
i. The location and configuration of your
antenna mount will determine the quality of
your signal; therefore, there are some
important factors to consider.
ii. Where will the receivers be located? Ideally,
the antenna will be centrally positioned
above that area.
iii.
Where will the transmitter or stationary
receiver/power amplifier be located? We
recommend that it be located no more than
25 feet (7.6 meters) from the antenna.
iv. Are there any metal obstructions in the area?
Ideally, there will be no metal between the
antenna and the receivers. Also, try to avoid
mounting the antenna in a location where
nearby metal would be in parallel with the
antenna -- this degrades the signal.
v. Will the antenna be mounted outdoors?
Antennas work well outdoors, but if possible,
try to place the antenna where it will not
receive too much exposure to moisture or
dirt. Covering exposed connections with
petroleum jelly or silicone gel will extend the
life of the antenna.

B. Antenna Orientation
i. The antenna's pattern is hemispherical,
meaning that it has an "active" side and a
ground side. The active side directs the signal
toward the receivers, so it is essential that the
active side be oriented toward the area where
the receivers will be used the Antenna
Module's ground side has the word "GROUND"
molded into the plastic
ii. See Diagram A. If it is necessary to locate an
antenna low on a wall, the ground side should
face down. If you are mounting a monopole
antenna in a ceiling or high on a wall, the
ground side should face UP. It may be
necessary to move the ground side of the
antenna mount around in order to accomplish
this.
i.
To move the ground side of the module, simply
remove the four nuts, reverse the module so
that the ground side is facing the bracket, then
re-attach the nuts. Be careful to not detach any
wires if the module opens while it is not
secured to the bracket.
