Thanks Shaky!

I noodled around and also found the following useful information:

There are two sections at the page below discussing antennas, including a photo of his attempt at a ground plane antenna for ADS-B:

I also found detailed instructions for a similar ground plane ADS-B antenna linked from here under "Your first ADSB Antenna":

You can make a pre-amp for about £4.

Take care how you feed in the power to it and make sure you provide a capacitor of maybe 100pf between the collector of the transistor and the input line to your receiver, else you won't do the RX any good at all.

Here is a really cheap one:

If anyone has had a go at making and using one of these can they please post the results, as in does it give a noticeable increase in range ? Thanks for any help.
