2 meter 8 + 8 XPOL element Yagi Antenna for EME – WSJT and MAP65 PA144-XPOL-16-4.5B

Excellent Super Low Noise 144 MHz XPOL Yagi Antenna 16 element. Stacked perfect for VHF Contests or EME.

Even with a single antenna you can work several EME stations via the Moon – EME.

With the polarization switch easy to change Horizontal, Vertical RHCP, or LHCP polarization.

8 + 8 element 2m – 144 MHz Low Noise Yagi antenna with the highest possible gain for its length. Great for Terrestrial VHF Contest or EME work.
