The ARRL handbook (you may be able to find one at your local library - or = whole books on the subject) has info on a number of different styles of = aerial/antenna. They normally have some plain language in them and formula for working out = the length. A 1/4 wave whip is usually the easiest to figure in size and = mounting - see another post for the formula.

I'm looking at using the TLP434 modules outside in an open field. I'd like to get the most range that I can. At least 150' but would be nice to get to ~600'. Anyway, I have no experience with RF, specifically the antenna.=20 As you can see, I'm a novice at this antenna stuff. I don't really want a whole bunch of analytical antenna design mumbo jumbo. Be nice if someone would say something like "Ya, just connect a piece of = 24AWG wire to the antenna that's about 3" long and that'll give you pretty good reception". Something like that.
