Installation
Installing the Antenna
The ANT-50 is housed in a white enclosure attached to a mast and mounting bracket that is to be secured
vertically to a pole or tripod. The antenna and GPS cable are pre-installed on the inside of the ANT-50.
The antenna can be mounted with the supplied clamps. Two different sizes of clamps are provided to
allow for various diameter sizes of the pole or tripod the antenna is being mounted to.
Provided there are no large metal objects to block the radio signals, mounting the antenna 6 feet high
is ok. Mounting the antenna 12 feet high is good. 20-25 feet is better.
LIGHTNING
Receiving lightning signals does not cause lightning to strike. Your ANT-50 is less likely to be
struck by lightning than your anemometer, since the antenna does not need to be above the
roof line. Still though you must exercise common sense when choosing a location for your
antenna. If you mount the antenna on a ten foot pole on the highest point on your roof, with
no trees or television tower nearby you are asking for lightning to strike.
Your best protection against lightning is to mount the antenna indoors. Radio waves will pass
right through a wood building. Lightning is more likely to strike a tall tree, television antenna,
copper plumbing vent, satellite dish, telephone line, power lines, or CB antenna. If you do
mount the antenna outdoors make sure there are plenty of ground paths for lightning nearby
(such as those just mentioned), and higher than the antenna.
The LRX-1 receiver board has surge suppression in its input to protect against voltages
induced into the antenna cable. It is also a good idea to purchase a surge suppressor to plug
your computer into. If you have a network card try to find one that will protect your LAN
line as well. Both your computer and surge suppressor will need to be grounded.
