Description: Antenna is a full size 5 element computer optimized
yagi with all the same hardware and features as our larger models.
This model has a 1/4" dia. driven element and T match rods.
Other elements are 3/16" dia. , all elements are solid rods.
Aluminum members are 6061 for best corrosion resistance. All
hardware is stainless steel except the two U bolts. 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 and good matching.
Antenna is very broadbanded with respect to SWR and radiation
pattern which means it will perform well on the low end or high
end of the band for SSB or FM operation. Can be mounted vertically
or horizontally and mount can be moved towards the center if
preferred.
