Need help setting up antennas

(1/1)

mikka:
Hi all,

I am looking at purchasing a 30 meter wind up tower, and if i get it wanted to get 4 FM radio antennas and set them up on the tower directed North, East, South and West.  Is this a good idea?  And if i did it would i have to space them apart at a certain distance?

Cheers,
Michael

Is this for listening to airband or the FM broadcast radio band?

mikka:
Gday mate,
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:

Not sure how easy it is to get these in Australia, but surely there is some equivalent down there.
