Introduction The BiQuad antenna is fairly easy to build and provides reliable gain and it has very forgiving design. You can make quite a big margin of error in the construction and still get 10-11dBi gain. Hence here is the Double BiQuad Antenna and BiQuad Antenna calculators for handmade antenna based on average data. However I highly recommend to follow my instructions, which are based on computer antenna simulation software 4nec2, to maximize performance. Is listed currently available instructions, simulated with computer software, for handmade 13-14dBi Double BiQuad external antenna. Note: The dBi scale is logarithmic in base 10, where +3 dBi is a doubling in gain!

This idea is not new and has many names such as shell cell, cantenna, bazooka antenna, canned antenna and tin can annie. We like to call it a recycled waveguide antenna. Whatever you call it, it is an interesting project that takes very.

An increase in gain of +1 dBi is equivalent to an increase of 26% and +2 dBi is equivalent to an increase of 60%. This means that the increase in +1dBi is a big deal.

Long cable will defeat the purpose of the antenna. Read the guide for more info.) • Copper wire for the element.

• Spacers in each end of the element to hold its position and spacing correct height between the radiator and the reflector. Spacers must be from any non-metallic material. Plastic will do alright.

There are plenty of tutorials for these steps:, or (Note: all calculations in links are for 2.4 GH z WiFi antenna. Use calculator calculated data and measurements for your antenna.) (Note: Pictures below not to scale) Element bending.

Does anybody know the so called 'LTE800-Dual-Quad-Antenna'? This kind of antenna looks similar to a BiQuad but works like a Quad-Antenna only and allows MIMO and it is polarized H+V. You can see it here: (scroll down) The two halfs of the antenna are connected in the middle like a 'U'. Its covered in the shown picture. I´m very much interested in how to calculate such an antenna bcoz that´s an easy way to use it as a feed-point of a satellite dish. If you can help please mail to: sybille.koch[at]gmx.at Thank you!
