When the weather gets warmer I'm considering one of these:-

It seems to have good possibilities connected to an SDRplay. The 390 Ohm resistor can be a low wattage carbon.

I also like to give this antenna a try. Already made the balun and have the metal box with the resistor.
I`m looking for the two masts for the construction and the give it a try.

Hi,
I use a T2FD antenna, and have some actual results from it you can look at here:

This is a short article on using an SDR as a RFI survey tool. Almost every spectrogram shown was taken using a BWD-90, T2FD. It is wide band, and about 6 db down from a dipole... I love it, and use it all the time for both SDR, and normal Ham use...
