Yagi Antennas |
![]() The SY206/EB antenna consists of a six-element yagi of outstanding durability and performance. All elements including the folded dipole are maintained at DC Ground potential for lightning protection. All elements on this antenna are attached to the boom with solid cast aluminum clamps. This highly versatile antenna is supplied as a standard mount yagi, or, as an end-boom mounted unit. As with other yagis, this VHF antenna is available in multiple-unit arrays for added gain. Horizontally or vertically parallel kits of 'H' frames can readily be supplied to mount two or four yagis with a common feed. SY212/EB The SY212/EB is specifically designed to meet medium gain
requirements. This rugged three-element antenna can be provided for conventional or
end-boom mounting and may be stacked for added gain. All elements are at ground potential
for lightning protection. |
