Hy-Gain TH3-MK4 Tri-Band Beam Antennas are 3-element, 3-band beam antennas designed for operation on the 20, 15, and 10 meter Amateur bands. TH3-MK4 antennas use Hy-Gain's full-power capable "Hy-Q" traps, a rugged boom-to-mast bracket, and all stainless hardware. Hy-Gain TH3-MK4 Tri-Band Beam will mount on a standard mast up to 2 in. O.D. mast and can be rotated with Hy-Gain CD- 45II or HAM-IV rotators. These antennas are ideal for DXpeditions and base stations alike!
