This Yagi should be used with a 1:1 balun for best performance and to help eliminate TVI. One good suggestion is the "Ugly Balun Project" as seen on this site. It works great and is very easy to build from coax and PVC pipe and a few plastic wire ties.

14 MHz – 14.35 MHz Full Size Heavy Duty Ham Radio Yagi antenna. For 20-meter competitions and DX-ing. High gain, High power, wideband operation antenna, low SWR, excellent F/B. Excellent mechanical properties.

2 Antennas 20M4DX HF Monoband Beam Antennas are full size, 4 element, 20 meter Yagis that leave the competition in the dust! The engineers at M2 Antennas used computer design techniques, and verified with NEC programs and range testing, that their 20M4DX beams have superior gain performance figures to the other 4 element Yagis on the market.

The HexTenna Yagi Beam by Alpha Antenna® is a 2 through 20 meters, legal limit, and full-size portable VHF/HF system for amateur ham radio and continuous coverage from 144-13.950MHz for military operations.

This 6 element 20m Yagi gives you tremendous performance with a very high gain on a 42ft boom. The antenna has been optimized for good F/R and SWR performance across the band. The antenna comes with our high quality, heavy duty materials and hardware.

M2 Antennas 20M5LD HF Monoband Beam Antennas offer the pure performance of a full size 5 element Yagi for world-class competition and DXing. 20M5LD beams have a clean pattern and great gain across the band, making them one of the best choices on the market, of all long-boom 20 meter monobanders.

Prevents binding, corrosion and the formation of aluminum oxide, and allows easy dismantling of antennas after several years. • Copper conductive grease: Professional conductive grease with a copper base, recommended for all hardware requiring a sound and lasting electrical contact.
