Right now I am looking at modifying a unit that receives 850, 900
frequencies.
What I am curious about is the concept of small antennas only in
reverse.
A small antenna might be a autombile antenna used for AM reception.

So, taking the unit to receive 850, 900 MHz freuquences, how well
would it receive 2.4 GHZ frequences?
It would seem that it would receive 2.4 GHZ well due to the concept of
effective length but I am not sure.

Any comments?

Thanks, Dave
