In the next few pages, I'll provide pictures and information about our products. Meantime, below you'll find a brief history of the cubical quad.
A cubical quad antenna is a four sided, square version of a folded dipole. In 1947, cubical quads began gaining popularity with amateur radio operators. According to Bob Heil in his book, Heil Ham Radio Handbook, there were articles in QST and CQ magazine showing how to build a 10 meter quad. These antennas are extremely directional and have considerable gain over other antennas such as the Yagi. Being made of light weight materials such as fiberglass and wire, make building, handling and installing the antennas an easy task. Quads can be designed for use in the VHF, UHF and HF amateur bands.
Over time, cubical quads lost some of their popularity but recently new hams have rediscovered them and they are becoming popular again.
For a complete history and technical information about the quad, one should read the book, All About Cubical Quad Antennas, by William I. Orr, W6SAI and Stuart D. Cowan, W2LX. A quick search on Amazon or Google should tell you where to purchase the book if it's still in print.

Like a Yagi–Uda antenna ('Yagi'), a quad consists of a driven element and one or more parasitic elements; however in a quad, each of these elements is a loop antenna, which may be square, round, or some other shape.It is used by radio amateurs on the HF and VHF amateur bands.

ABOUT ME
My name is Randy and I love quad antennas. In fact, I've been building them for over 40 years. To me, you just aren't going to find a better antenna. Every Ham finds an aspect of radio that interests them. Some it is contesting, QRP, or digital. My favorite thing about Amateur Radio is antennas. I have always experimented and built my own antennas for my 40+ as a ham. I have learned through trial and error what works and how to make my antennas as efficient as possible. I started selling my quads in the 80's and have perfected my designs and dimensions and it only took 25 years.
