Yeah it is for air band. Not getting the 30 meter tower now i am going to set up a 6 meter tower this weekend. But would it be good to set the FM antennas up pointing N E S W. Or would i need airband antennas?
Use airband antennas. Either that, or directional log-periodic scanner antennas covering the right frequency range. It all depends on what else you would like to monitor besides airband.
I've had good success with these:http://www.grove-ent.com/BEAMII.html
Not sure how easy it is to get these in Australia, but surely there is some equivalent down there.
