LPDA orientation when receiving GPS signals on USRP2

GNU Radio

Hi everyone,

Does anyone know what the orientation of an LPDA (log periodic dipole
antenna) should be when receiving GPS signals?

Should the up-most element be the longest one, or should it be the
shortest
one? In other words

From ARRL Antenna Handbook (1988) the ‘forward’ direction is towards the
smaller elements on an LPDA. Don’t think that JCM equations have changed
since '88.

     Kind Regards,

Point the short side (with the connector) towards the source you are
trying to receive from.

A log periodic antenna is not ideal for receiving GPS since GPS is
circularly polarized and the LPDA is linear.
