Biquad as a dish horn?

[Guest]

Directivity is the name of the game today.

 

I'm trying to do some long range 2.4 GHz. I have a friend who can sell me a big ol' satellite dish (~1 meter diameter).

- A bi-quad is cheap and efficient, but is it the best of the bunch.

- Cantenna's are much harder to make here, no tubes of proper size available locally. 

- Maybe a rectangular wave-guide? Would be easy to machine out of some clean, reflective copper.

- Yagi's are nice and easy, but if one has so much room for imagination, why not go straight for gold?

 

Aiming for first few channels of 2.4 GHz range (2420 MHz?). Most routers seem to default to it.

,,, put a Batwing antenna in the focus of the parabolic satellite dish ... !!!

Then it must be this one.

Thought you were joking for a second, there. How wrong I was...

This must be the easiest 12 dBi out there.

Thx

Batwing antenna and offset dish...

,,, and impedance .... ???
,,, why don't you give the dimensions...???

,, and why not .. ???

,,,or so..

any details contruction Sir?

[Admin 2545]

 I don't think this type of adaptation covers a high frequency band with an impedance of 50 Ohm...

IHi could I use an offset parabolic dish 65 cm with a coax collinear antenna 5dbi  as a feeder how can I use the antenna vertical or horizontal I need more information about this  and 

[Admin 2545]

,,,,,how it looks coax collinear antenna 5dbi ...????

[Rtyon 1]

it look like an antenna that exists on routers it's omnidirectional 5dbi  can I use it as feeder on an offset parabolic dish  65 cm how to use vertical or horizontal 

[Admin 2545]

,,,the offset dish must be placed like this...

 

[Rtyon 1]

 Yes I know how to insall the dish but cani use omni directional antenna to feed  the dish

[Admin 2545]

,,,,yes, but behind the omni antenna, you need a conical,elliptical, paraboloid reflector...!!!

 

,,,the simplest conical reflector...

Will I install the omnidirectional antenna vertical or  horizontal  on the dish
