Hi All,
I've been following closely the OFDM- and related TX/RX issues.
If you TX sumthing, build/buy an (directive) antenna for your target
frequency and point it at the RX usrp.
I suggest a Yagi, helix or a parabola for TX:ing, cost ~$10 at your
frequency. Apply to RX the same.
Using a whip is trouble if you do not know....
An antenna sure can be *omni* to detect the signal, to demodulate it
perfectly is another thing.
Example: TX is a RHCP (right hand circular polarized) signal.
RX it with a VP (vertical polarized) antenna, it wont demodulate properly.
A user receiving 137 MHz RHCP satellite data posted *his ultimate antenna*

It aint that complicated, trial and error does it.

Patrik
