2.4 Antenna Position.

[flyer88]

Just read an interesting article on 2.4 radios with different antenna positions and how it effected the output of the coverage.

It stated that the transmission from our radio will look something like a dough nut. The middle of the dough nut is the antenna and depending on the position of the antenna it varies this imaginary dough nut shaped radiation pattern.

If you were to slide the hole of the dough nut over your antenna, you can now visualize the approximate radiation pattern. Therefore the most coverage would come from your antenna bent vertically 90 deg. Like this you would be standing in the middle of this large dough nut shape and the radiation could be as far as 2km.

Food for thought.

That is interesting and I was wondering about that antenna position, seemed kind of 'interesting'.

Hmm...
Read something about why the antenna was bent but didn't quite follow it. Now that you put it in relation to food, it's crystal clear. Actually it is easier to understand, thanks.

To make it more clear the LEAST effective way to point your TX antenna is straight at your plane. The best way is at a 90 degree angle.

On a side note you can test for range limits this way a bit. Fly your plane more or less straight over head. Point the antenna straight at it. If it starts losing connection turn it to 90 degrees and should get control back. If the plane gets too small to even tell then your connection should be good unless you have some interference.

I pass this on THEORETICALLY. The principal makes sense. I've tried it but have only reached the point of the plane getting so small I couldn't tell what it was doing. I have never had it lose contact and then successfully regain it so don't know from personal experience if that will work. Do so at your own risk.
