6 meter 2 Elements Rear Mount Antenna 6m2DX1R

50 MHz small Yagi antenna 6m2DX1R – PA50-2-1.4RB. In the box is everything included. Antenna + balun with connector + bracket… Elements are tapered to reduce vibrations at high winds. 1.4 meter long boom. Excellent antenna for balcony or put on the side of the tower.

Since this Ham Radio antenna has 2 elements it very easy to set up. Antenna is very good for field day with light-weight construction or even for permanent setup.

This Ham Radio antenna has widest possible azimuth radiation pattern. 50 MHz 2 element Yagi is good for vertical stacking in permanent setup since this wide angle allows listening to ham radio stations without frequent rotator movement. It is good for E-sporadic season since when there is an opening you don’t need much gain for it.

6m2DX1R (PA50-2-1.4RB) dipole appearance. Balun and Connector are included in the antenna.
