Will accept mast sizes from 1 1/4" to 2" dia.
Seperate feedlines are needed for each
set of elements or a relay box mounted near the antenna You cannot
feed the antenna with jumper to each set of elements and then
into a T connector.
Antenna is a full size 32 element wide spaced computer
optimized yagi. Has machined aluminum connection box as the core
of the antenna feed system. This box is silicone gel sealed and
opened if something needs work or repair in the future yet it
is extremely rugged and provides excellent shielding and protection
from the elements for the internal connections. To give our antennas
a little better bandwidth SWR, we make the driven element a larger
diameter. This model has a 1/4" dia. driven element. Other
elements are 3/16" dia. , all elements are solid rods. Aluminum
members 6061 for best corrosion resistance. All hardware is stainless
steel except U bolts which are zinc plated. Uses a 4:1 coaxial
balun which allows the balanced feed of the antenna to be fed
with 50 ohm unbalanced coaxial cable and uses superior T match
system for best radiation
pattern. The holes that accept the elements are reamed .001"
dia. oversize in order to allow the rod to be inserted but at
the sametime maintain zero clearance around the rod when the
screws are tightned.
Our antennas are designed to withstand the most severe enviornments
while performing to specs.
