Why should there be a problem with this? The tests of the Linx
receiver in Chicago, DC, and Ottawa, and the tests of the
prototype LG, were all done with simple monopole and dipole
antennas, on sidewalks, parking lots, and indoors. I don't
know why we're still fretting about portable reception,
especially the outdoor variety. Portable reception has been
demoed time and time again. The problem is getting the better
receivers on store shelves.
By the way, Doug's idea of an omni receiving antenna with gain
should work very well with receivers that have good enough
equalizers to make use of echo energy. The best antennas in
that case are the least directional, as the LG prototype tests
showed.
