Half Square Radiation Patterns

The Half Square antenna is a great wire antenna for the DX edge. No need for a tower, rotor, and beam to get rare DX or be competitive.

The Half Square antenna is a wire antenna with two vertical radiators fed in phase. One vertical element (1/4-wave) is fed at the top where it is attached to a SO-239. The other side of the SO-239 is attached to a horizontal half-wave phasing line and then connected to another vertical element (1/4-wave) aiming down to the ground. So basically what you have is two vertical elements spaced one half-wave apart and fed in phase. This will produce a bidirectional radiation pattern with almost an S unit of gain, compared to a dipole, broadside to the antenna. Seeing this antenna is fed at the top of the vertical element, the current portion of the antenna is high in the air where it really counts. The antenna is a direct match to a 50-ohm system so there is no need for a matching network.

As with all of our Hy Power antennas, this model will also handle the legal limit and is made with all of our Hy quality antenna components.

Baluns are optional.

If you order an antenna and would like a balun installed on your new antenna,

we can do that for your at no extra LABOR charge.

Baluns keep the RF off of the outside shield of the coax and put it on the antenna, where it belongs!

If ordering multiple items, such as a Half Square with a balun installed or two antennas,

please call or email us for an adjusted shipping rate.
