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! 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. Double BiQuad Antenna Calculator. Dunhill rollagas lighter repair manual free download programs. ( Very important to choose proper cable! the longer the cable length, the more signal loss you'll have through the cable. 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.

For information on connecting a biquad antenna to a wireless radio, have a look at the page on using wireless antennas. When using a biquad to establish a link to another wireless device, you should ensure the polarisation of the biquad is the same as the antenna you are connecting to.

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!
