HexTenna vs HexTenna Yagi and their differences
The HexTenna Yagi will not function as a Vertical but can be used as a 2-20M Yagi and you can also use the driven side by itself like the HexTenna as a Dipole by leaving the reflector elements installed as a counterweight. Only the HexTenna Vertical and Dipole will function as both a Dipole or Vertical, covering 2 – 40 Meters, plus 220MHz, & 440MHz. You can tune either one by equally lengthening each element until resonance is achieved. REFERENCE: 2-20M HexTenna Yagi antenna vs a Vertical Dipole VHF HF HF HexTenna

Spoiler alert: Moving the HexTenna from the 5 1/2 foot HD Tripod to a 15-foot mast increases your signal by half (1/2) an S-Unit.

Very well built antenna and guys at Alpha worked really hard to get it to me for a light house activation. Thanks!
The Yagi HexTenna was packaged extremely well and its build quality which was exceptional. We also purchased the Hextenna Dipole with the similar results. We are also strongly considering the 10m-40m, 100 Watt MagLoop. Steve (Owner) has been extremely interactive with our
many questions and we wouldn’t hesitate purchasing any product from Alpha Antenna.
Great antenna system, easy to setup, really versatile.
