Dual quad wifi antenna




















I wonder if a sat dish with a triple biquad antenna would give even better gain. The double biQuad is about 12db to 14db and the Single is 10 to 12db. The sat dish, is a great wifi antenna too, I will build one soon. Thinking of going with a bi-quad antenna in a oval fish can. Having trouble finding a good place to mount the dish.

Under an eaves trough might not work. Chimney mount is better but harder to mount in the snow. Got plenty of hot spots Average tree tops are 60 70 feet high my dish on the chimney is 15 20 feet up. With the reflector installed it becomes a directional antenna with more gain.

This antenna can be used with vertically and horizontally polarized RF services. JavaScript appears to be disabled in your browser. You must have JavaScript enabled in your browser to utilize the functionalities of this website.

Here we see the rear of the collector plate, with the N-type bolted in place. Here is where we screw on the N-type to SMA adaptor. This is the N-type to SMA adaptor. There was an improvement of signal over my previous cantenna and the supplied stick antenna. Question 2 years ago on Introduction. Okay crazy question How about a half wave or a full wave biquad.

Is it better than the quarter wave one. I have never seen those on the internet. Reply 6 years ago on Introduction. You can use N or SMA connectors. If you have an SMA cable, it might make sense to use that so you don't need an adapter, but they are more fragile. Remember, you need to connect the back end of the element to the ground plane. You can use a regular screw if the connector doesn't use 4 screws like the one in the picture.

One question, do you get better performance from this with a single feed point vs the standard double feed point construction, or are both pretty close?

Very nice build! So many designs on instructables are terrible. Antennas are an exacting design requiring tight measurement and spacing to perform well at all. Your build shows people here how to do it right! I just got done making a 20 director YAGI beam and this high frequency RF is hard to keep the measurements in tolerance. Most designs in the MHz range has less than 1mm tolerance. Reply 9 years ago on Introduction. It all depends on your skills as a constructor, on if you use something like a dish to concentrate the incoming signal and on if you can shield noise out of the signal as much as possible.

I have since moved on to a Yagi, for which, I will produce an instructable in the future. I've been looking at more of these Bi-quad antennas and they seem to be connected to a cable dish, do they need to be connected to one to be able to receive signal or is that just for better signal?

The dish is for increased signal. You will get an improvement with a standalone bi-quad over the omnidirectional stick antenna. The mile was not amped, but the mile was. Reply 10 years ago on Introduction.
