SD24 Antena - Dipole home-made 27 dbi 2,4 Ghz.

Recommended Posts

Nice, but forget about this for R/C applications. A 27dBi antenna will have a 3-4° beamwidth, so figure out how precise you'd need to be at following a moving target :wacko:

Yeah it's a good solution, but achieving that much precision will be a hard task.

if beamwidth just got 4º then we can foget, true.

but you can always get a low diameter parabolic to get about 30º beamwidth,

maybe that post wasn't a very good idea, sorry.

The only time you could use it is at extream range when only a little movement will be required to keep it on target. Maybe auto tracking.

For most of us a 14dbi quad patch is the sensible limit for hand pointing.

too difficult to add a telescope very near to antena, (both in same pan a tilt servos i mean)

then control the telescope movements thru a computer, like "eyetoy" do, to identify movements?

something like that:

or

here is another way:

some celestron telescope's got a sofware to move it thru computer to selected site.

an air gps can send each second the location to computer and computer will move telescope to x,y position. (we glue the antena to the telescope)

well i know it's too much work and we really dont need it,

i was just tryng to find a solution even if it's complicated,

Some guys here have use gps through the audio channel to point their aerials.
