"@Cronselaar: Also, I forgot to mention if your goal is just a flat antenna, that can easily be done with regular round copper wire and dollar store foam board. I have seen Yagi-Uda, Moxon, and dipole loop antennas in this configuration,"

Jonathan Price replied to James Roney's discussion 433 UHF LRS Antenna "Turn Stile"
